Shiny Cowbird Seen a Second Time

On 07 October 2005, Daniel Martínez and Pablo Porras observed three male Shiny Cowbirds (Molothrus bonarienses) near Hone Creek, Talamanca (a few kilometers south of Cahuita). They were able to take several digiscope images, of which this is the best one. The bluish hints to the plumage would seem to rule out the otherwise similar, all-black Melodious Blackbird (Dives dives), which is now fairly common in the area, according to Daniel.

Readers may recall that on 26 April 2004, Daniel Martínez and Ernesto Carman reported seeing a female Shiny Cowbird, not far from where the three males were recently spotted. So, it would seem that the establishment of this species in CR may indeed be an inevitable event.

Throughout their range, shiny cowbird females are known to parasitize the nests of many different passerine species, including those of saltators. Thus, there is a certain irony in the spread of the Grayish Saltator (Saltator coerulescens) into the southeastern Caribbean lowlands. I was unaware of its occurrence east of Guápiles and so was surprised to encounter a pair of Grayish Saltators on the morning of 17 September, while birding the grounds of the Pizote Lodge, near Puerto Viejo de Talamanca. We saw the pair again the following morning feeding in the same fruiting fig tree.

I inquired of other local birders regarding the presence of Grayish Saltators in the SE Caribbean lowlands and was informed by Mariano Cruz that on 20 September, he saw a pair feeding on melastome fruits in the Valle de la Estrella.

Has this species reached Panama yet??



Pale-breasted Spinetail in Cartago

Daniel Martínez made another avian discovery while looking for newly arrived migrants on 11 September at the Instituto Tecnológico (IT), on the south edge of the city of Cartago. In addition to finding seven species of migrants, he was astounded to come upon a pair of Pale-breasted Spinetails (Synallaxis albescens) with two fledglings that were begging to be fed! This species is fairly common, albeit a skulker, in the southern Pacific portion of the country, but is completely unknown in CR outside of that area, with the lone exception of a bird mist-netted by Rachel Taylor near Río Frío de Guápiles in March 2003. I’d mentally chalked that one up as a stray individual (apparently there were no other captures), but now, a pair feeding young almost certainly indicates residency.

The strange thing is that Daniel, who lives in Cartago, has been birding the IT for five years or more now and has never even heard the spinetail there before (and they tend to be quite vocal). He’s quite familiar with the species from his time spent at the Wilson Botanical Garden, near San Vito, where he hears it frequently and was even able to take this photo in January.



Marbled Godwit and White-winged Doves Visit Tortuguero

In early September, Ian Thompson, who’s working with the Tortuguero bird monitoring project, found a Marbled Godwit (Limosa fedoa) on a sandbank near the village. The bird stayed around for at least a few days and was also seen by village resident, Daryl Loth. As far as I’m aware, this represents the first record for this species on the Caribbean side of Costa Rica.

And it would seem as though a couple of White-winged Doves (Zenaida asiatica) took the trouble to read the previous edition of the GBN, in which the spread of this species onto the Caribbean slope was reported. On 21 August, Alejandro Solano, while visiting and colaborating with the aforementioned monitoring project, saw two White-winged Doves on the airstrip gathering grit. When approached to within about five meters, they flew off and landed in a sea grape tree (Coccoloba uvifera). This constitutes the first report of the species in Tortuguero.

Interestingly, the following afternoon, 22 August, Alejandro and his colleagues came across a Mourning Dove (Zenaida macroura) on the soccer field in the village of Tortuguero. Hoping to photograph the bird, they went to get their cameras, but returned to find that an impromptu match was underway and the dove was nowhere in sight. This bird would be the second record for Tortuguero, with the previous being a sighting by Jim Zook on 11 September 1995. His bird was perched on a log along the beach by the Mawamba Lodge, before flying off towards the north.



Raptor Roundup

All three eagles have been reported during the last few months, as well as some other uncommon species. Here’s what I know:

On 18 August 2005, Mariano Cruz and a tour group he was with were treated to an excellent view of a Crested Eagle (Morphnus guianensis) near the entrance to Caño Harold in Tortuguero NP. The bird was perched some 12 meters above the creek and one of the tour members was able to video it.

On 28 August, while visiting Bosque de Paz, Noel Ureña and Pieter Westra had great looks at a Solitary Eagle (Harpyhaliaetus solitarius).

Randall Ortega mentioned in an email that a Harpy Eagle (Harpia harpyja) was seen and photographed on the Pacific side of La Amistad International Park, at an elevation of 1900m.

Mathias Kümmerlen reported seeing a pair of raptors soaring over the western portion of the Central Valley on 10 August. He described them as “completely white below with a contrasting black border to the wing edge, from the primaries to the tertials. Likewise, the tip of the tail. They were large birds with wide wings and short tail.” He also mentioned having seen two very similar birds about a year ago. Although his guess was that they were White-tailed Hawks ( Buteo albicaudatus, he was hesitant to call them as such due to the comment in the field guide regarding the status of this species as “formerly locally in central highlands, but no recent records.”

To complicate matters, the field guide does not illustrate the very similar-looking pale phase Short-tailed Hawk (Buteo brachyurus) in flight. This is one of the most commonly seen soaring hawks over the Central Valley, as well as most of the rest of the country at low and middle elevations. However, Mathias mentioned the key diagnostic features in his description: the noticeably wide wings and short tail of White-tailed Hawk. In fact, despite the common name, the tail of a Short-tailed Hawk in flight is not remarkably short, whereas, that of a White-tailed Hawk is!

Responding to Mathias’ email, Julio Sánchez affirmed that he has seen White-tailed Hawk over the eastern portion of the Central Valley, south of Cartago, and also mentioned that raptors frequently engage in local movements. [Ed. note: See more on this species in the following article.]



In Search of the Ocellated Poorwill and Other Rarities

Reading through A Guide to the Birds of Costa Rica, by Stiles and Skutch, one of the more tantalizing species has to be the Ocellated Poorwill (Nyctiphrynus ocellatus), which is “known only from a small, recently discovered breeding population near Brasilia, in the extreme NW corner of the Caribbean lowlands.” At least it made a suitable excuse to organize a small birding expedition to that relatively unexplored area of the country.

On 19 August, Kevin Easley, Robert Dean, Andrew Keaveney, and I drove up the PanAmerican Highway towards the Nicaraguan border and then headed east to Santa Cecilia. In terms of biogeography, this is a fascinating sector of the country. The change from the Pacific to the Caribbean slope is completely imperceptible and changes in the vegetation (heavily altered along the roadside by human activities) are likewise negligible. Nonetheless, there are some noticeable changes in the avifauna. For example, just west of Santa Cecilia we observed an Olive Sparrow (Arremonops rufivirgatus) and the Pacific race of Variable Seedeater (Sporophila aurita aurita). By the time we’d reached Brasilia, just over 10 kilometers to the southeast, we were seeing Black-striped Sparrows (Arremonops conirostris), the Caribbean race of Variable Seedeater (S. a. corvina), and the birdlife was decidedly of Caribbean distribution.

As we continued towards the village of Dos Ríos, checking out the habitat for promising-looking poorwill areas, we were treated to an awesome natural spectacle as the crepuscular rays of the sun iluminated a mushrooming cloud.

Once daylight faded, we began listening for the poorwill and playing the recording that Kevin had—presumably made somewhere in South America. We were treated to great looks at a very obliging Vermiculated Screech-Owl (Otus guatemalae), one fly-over and several calling Crested Owls (Lophostrix cristata), and what must have been more than 50 Common Pauraques (Nyctidromus albicollis), but alas, not a peep out of the poorwill. And poor us, as the clouds let loose with a downpour that signaled the end of our nocturnal efforts.

We concur with the opinion later given by Julio Sánchez that it would be best to try again sometime in the drier months of March and April, when the birds ought to be vocalizing.

On 20 August, we completed our loop around Orosi Volcano by driving from Dos Ríos to the PanAm Highway at Potrerillos, stopping en route at the San Gerardo Biological Station just outside of Dos Ríos. Although we only spent an hour and a half on one short forest trail, the site showed potential—reminding me of Las Heliconias above Bijagua de Upala with a mix of species that included Spotted Antbird (Hylophylax naevioides), Long-tailed Manakin (Chiroxiphia linearis), and Song Wren (Cyphorinus phaeocephalus).

Midway between Potrerillos and Liberia, I noticed a soaring hawk and had just about got the words “Short-tailed Hawk” out of my mouth when the bird banked, giving a look at its upperside and immaculate white rump and tail base! Kevin did an impressive U-turn and within moments we were all out of the vehicle and training our bins on a handsome, low-flying White-tailed Hawk (Buteo albicaudatus).

Back in the vehicle and comparing experiences with this species, it turned out that between Kevin, Robert, and I, we combined a total of five previous sightings of White-tailed Hawk in Costa Rica, all of them in the Guanacaste lowlands. Definitely not a common raptor!

We ended up that afternoon on the slopes of Miravalles Volcano, above the I.C.E. geothermal plant by Las Hornillas, hoping to find Rock Wren (Salpinctes obsoletus), Rusty Sparrow (Aimophila rufescens), Botteri’s Sparrow (Aimophila botterii), or Grasshopper Sparrow (Ammodramus savannarum). As the rest of us birded from the edge of the gravel road, Kevin strode off into an overgrown, brushy field and returned with word that two Rusty Sparrows had flushed in front of him. A steady, hold-on-to-your-hat wind blew light rain on us as we tromped around in the brush, trying to refind the sparrows (or anything else of interest, such as the Lesser Ground-Cuckoo (Morococcyx erythropygius) or Thicket Tinamou (Crypturellus cinnamonmeus) that called intermittently). Eventually, wet and tired, we conceeded defeat.

Returning to the same spot (about 100 meters after a large quarry) the next morning, it didn’t take but a few minutes to find a Rusty Sparrow perched in a small shrub and singing away. And we didn’t even have to leave the road to get good views! In about 30 minutes, we saw at least four individual Rusty Sparrows—compare that with the effort that Paul Murgatroyd and I put into seeing this species a year earlier

Kevin and Andrew had to get back to Alajuela that afternoon, but Robert and I decided to spend another day in pursuit of new and/or rare birds. So we hired a car in Liberia and drove to Filadelfia, where we gotdirections to La Guinea—the site where Jim Zook had discovered Tricolored Munia (Lonchura malacca) back in 1999. As we drove along a drainage ditch, heading towards the sugar mill, we saw at least 50 White-collared Seedeaters (Sporophila torqueola) and perhaps even twice as many Blue-black Grassquits (Volatinia jacarina), but no munias. Fortunately, I was able to get a cell phone signal and find Jim at home on that Sunday afternoon. Jim suggested that we check a little gravel road leading to the Tempisque River (more or less across the street from the school), and sure enough, within less than five minutes we were looking at three males and a female munia calling and foraging in tall stems of seeding grass. [As I write, the entire village of La Guinea is under a meter or more of water from the flooding Tempisque, but since this happens most years, I guess that the munias can take care of themselves.]

On Monday morning, 22 August, we were at some salt ponds outside the village of Colorado de Abangares at sunrise. The tide was high and so there should have been plenty of shorebirds, but the activity was a bit disappointing. Perhaps it was still a little early in the season for many species. Nothing really out of the ordinary to report, but we did find this individual foraging among some smaller Calidris sandpipers. Any guesses?



Migrant Reports

It’s that time of year again when it gets hard to concentrate sitting in front of the computer because you can’t help but wonder what things new and different might be flitting about out in the yard. Yes, one never knows what North American migrants might have newly arrived each day, but amongst the many species partaking in the annual peregrination, here are some of the more interesting reports that have reached me:

American Golden-Plover (Pluvialis dominica): On 14 September, Willy Alfaro and Gustavo Flores spotted a bird at the shrimp ponds in Chomes.

Snowy Plover (Charadrius alexandrinus): Ditto the above, and also, on 10 October, Daniel Martínez found an individual at the mouth of Hone Creek.

Buff-breasted Sandpiper (Tryngites subruficollis): On 25 August, while walking the beach at Playa Azul, just south of the mouth of the Tarcoles River, Andrew Keaveney came across a lone bird in the grassy strip between the sand and the mangroves.

Blue-and-white Swallow (Notiochelidon cyanoleuca): On 29 August, Jim Zook saw three birds at Chomes. Given the location and the time of year, it’s likely that these were austral migrants of the South American race.

Blue-winged Warbler (Vermivora pinus): On 28 September, Jim Zook spotted this species at Los Cusingos, the farm of the late Dr. Alexander Skutch.

Golden-cheeked Warbler (Dendroica chrysoparia): On 22 October, Pablo Elizondo and Herman Venegas had the fourth CR record of this species and the first male for the country while birding at an elevation of 1850m on Silent Mountain (Silencio) above Platanillo, southeast of Turriabla. They watched the bird for about five minutes as it foraged with Spangle-cheeked Tanagers (Tangara dowii) and Sooty-capped Bush-Tanagers (Chlorospingus pileatus).

Blackpoll Warbler (Dendroica striata): During their lunch break on 09 September, Julio Sánchez and other workers at the National Museum were entertained by the presence of six species of migrant warbler in the museum garden. Three of the species were new for the garden list: Cerulean Warbler (Dendroica cerulea), Yellow-throated Warbler (Dendroica dominica), and Blackpoll Warbler. The first two are uncommon passage migrants, but were seen at a number of locations this season; the latter is even less common and this was the only report received. Julio said that the best part of the entire spectacle was having two Black-and-white Warblers (Mniotilta varia) present in the same group for text book comparisons with the Blackpoll in terms of both morphology and foraging tactics.

MacGillivray’s Warbler (Oporornis tolmiei): On 10 October, Jim Zook had two birds to report from Cerro Espiritu Santo, near Naranjo de Alajuela. And on 25 October, while birding with Daniel Jacobson, David Chaffin, John Henderson, Tommie Rogers and Edge Wade, we came across a young male along the edge of the La Peninsula road in Arenal NP.

Hooded Warbler (Wilsonia citrina): On 17 October, while waiting for the plane at the Tortuguero airstrip, I found a handsome male in the undergrowth of the wooded area just north of the runway.

Yellow-breasted Chat (Icteria virens): On 23 September, Rafa Campos encountered a bird in La Argentina de Grecia. And on 02 October, Jim Zook found a chat in a coffee plantation shaded by Eucalyptus trees, near the Corinto River along the PanAmerican Highway between San Isidro and Buenos Aires.



Hummers Go “Off the Map”

Maybe it’s because it’s been a very wet September/October with tropical waves, depressions, storms, and even full-blown hurricanes causing lots of precipitation, principally on the Pacific side of CR. Or maybe it’s just because there are more observers out and about each year and detecting things that had not been noticed before—certainly, hummingbirds as a group are well known for their altitudinal movements here in the tropics. But whatever the reason(s), there have been a number of recent reports of local hummingbird species turning up in unexpected places.

The first news came on 27 September, when Daniel Solano wrote to tell of having observed a Brown Violet-ear (Colibri delphinae) at El Rodeo that morning. Daniel was birding with Eduardo Carrillo on the dirt road leading to the Jaris River, when they noticed the bird feeding in a hedge of white-flowering Megaskepasma erythroclamys, where it was repeatedly chased by male Blue-throated Goldentails (Hylocharis eliciae) that vigorously defend stretches of the exotic shrub. This apparently is the first record of Brown Violet-ear for El Rodeo, at an elevation of about 800m.

Curiously, Jim Zook later reported that on 28 September, he saw two individuals in a flowering Symphonia glabulifora at Los Cusingos. This was the first time that Jim had seen Brown Violet-ear at Dr. Skutch’s, and it would be interesting to know if Dr. Skutch ever recorded it himself on the property.

While visiting Savegre Mountain Hotel in San Gerardo de Dota from 10 to 12 October, Paco Madrigal had a couple of surprise sightings. On 11 October, just 150 meters down the road from the hotel gate, he discovered a Snowy-bellied Hummingbird (Amazilia edward) feeding in Fucsia arboresens. The bird remained in the same area until at least noon the following day.

Still amazed at finding a Snowy-bellied Hummingbird at some 2200m, Paco was stunned to come across a Violet-headed Hummingbird (Klais guimeti), likewise feeding in Fuscia, just another 100 meters farther down the road. This bird was also present the next day.

Julio Sánchez said that he has seen both of these species at nearby Providencia de Dota, but at a somewhat lower elevation of about 1700m.

When the phone rang on the evening of 14 October and it was Marcos Soto calling from Savegre to tell me of some odd hummingbird sightings he had had that day, I smiled to myself and said over the phone, “Snowy-bellied and Violet-headed Hummingbirds, right?” Taken aback, he replied that yes, he had seen a Violet-headed Hummingbird, but no Snowy-bellied, rather he had called to report a male Charming Hummingbird (Amazilia decora) that had been feeding on Fuscia behind the lower cabins! At 2200m, this is much higher than any previous elevational record for the species.

And although White-tailed Emeralds (Elvira chionura) are known to show up at Savegre, I’ve never heard of more than one or two individuals being present at a time. So it came as a surprise to me when Marcos also mentioned having seen at least three female and two male emeralds around the lodge that day.

During a two-day visit to the area on 28 and 29 October, we found a male and female emerald, but none of the other above-mentioned rarities. However, we did encounter a female Stripe-tailed Hummingbird (Eupherusa eximia), a species which I had never seen before in the valley.

On the Caribbean side of the country, on 09 October, Daniel Martínez spotted a female Magenta-throated Woodstar (Calliphlox bryantae) from the observation tower at Kekoldi. This is the second record for the species at the site—Jim Zook saw a female at about the same time of year last year.

And finally, during a stop at the Mirador San Fernando in Cinchona on 15 August, we were told of an albino hummingbird that had been visiting the feeders for at least a week. It didn’t take but a few minutes before the aberrant bird showed itself and I was able to shoot some video. Based on size and bill shape, we suspect that the bird is actually a Green Violet-ear (Colibri thalassinus). Here is a video grab with a Brown Violet-ear (in flight) for beak comparison. When I last visited Cinchona on 27 October, we did not see the bird and were told that it had not been seen recently.



New Rosy Thrush-Tanager Site Reported

Once again, Jim Zook has made an important discovery by finding “a place full of Rosy Thrush-Tanagers (Rhodinocichla rosea)!” The spot is along the road from Buenos Aires to the Dúrika Biological Reserve, about 11.5 km from the Buenos Aires High School (Colegio), or in other words, a few kilometers beyond the savanas of Alto Salitre where Jim has found Wedge-tailed Grass-Finch (Emberizoides herbicola). Jim recently heard about six thrush-tanagers singing from the undergrowth of brushy areas along a ridge, near a sign that reads “Reserva Biológica Dúrika 3.5 km.” The site is at about 1200m, which puts the birds significantly higher than the 900m that the field guide gives.

Jim added, “To make things even more interesting, there’s a fellow named Eugenio from the Reserva Dúrika who knows his birds well and claims that Pheasant Cuckoo (Dromococcyx phasianellus) is quite common in the area!”



Changes at Los Cusingos

Nature unleashed her fury in mid-July when a tornado ripped through Los Cusingos knocking down many trees. Apparently, no damage was done to the house where Dr. Skutch lived, nor to any of the neighboring dwellings in the area of Quizarrá. However, the damage to the forest patch was extensive. Nonetheless, Jim Zook reported that most of the trails have now been reopened.

In related news, the restauration work has begun on Dr. Skutch’s house and Noel Ureña recently sent these images to show how the work is progressing.



Cocos Island Trip Offerings

For those of you who have expressed interest in the possibility of getting out to Cocos Island to search for the three endemics and the various pelagics that occur there, two trips are currently scheduled for 2006.

The Organization for Tropical Studies will again be offering a trip to the island from 29 April to 06 May. The cost is $1650 per person in standard staterooms and $1850 in suites. For more information and bookings, visit the website (in Spanish only, it seems).

In October 2006, Mike Boatwright of Tico Tours is planning a trip for birders aboard the Undersea Hunter, a live-aboard dive vessel that can accommodate 12 passengers. Due to the small group size, the per person price will be about $4000, but it will also be a slightly longer trip. The proposed dates are 17 – 27 October 2006. Interested birders should contact Mike at for more info.



Christmas Bird Counts Coming Up Soon

Here are the dates and contact information for the various CBC activities that traditionally take place in Costa Rica—at least as much as I’ve been able to find out. All interested birders are welcome to participate. Hope to see you out there!

Cartago: 11/12/05 Julio Sánchez <> 551-2509

Aerial Tram: 15/12/05 Daniel Torres <> 711-0018

Grecia: ??/12/05 Rafael Campos <>

Monteverde: ?????

La Selva: 30/12/05 Rodolfo Alvarado <> 766-6565

Fila Costera: 03/01/06 Noel Ureña <> 771-9686

Also, a new count is being inaugurated this year in the Carara area. It will not be an “official” CBC, but that in itself will allow for an early scheduling so as not to conflict with other existing counts. The date will be 03 December 2005 and anyone interested in participating may contact Randall Ortega < > 643-1983, or 846-8621.



Mystery Bird Photo Quiz

Congratulations to Pieter Westra, Bill Tice, Soo Whiting, Eduardo Amengual, and Pablo Elizondo for having correctly identified the mystery bird from the previous edition of the GBN. Admittedly, immature hawks are often a challenge to ID, and the photo didn’t offer much help, apart from a streaked head and yellow cere and feet. So, here’s a view of the same juvenile Broad-winged Hawk (Buteo platypterus) showing the characteristic dark malar stripe.

Now that fall migration is in full swing, here’s a photo that I took from the observation tower at the Kekoldi Hawk Watch site, near Hone Creek, on 17 September 2005. Can you identify both species? The answer will be announced in the January 2006 newsletter. Good luck!



Thanks to everyone who contributed news of rare sightings and good finds. I hope that you've enjoyed this newsletter and welcome any comments at or if you're in Costa Rica, feel free to give me a ring at 293-2710.

Wishing you all great birding,

Richard Garrigues
