Unknown all-dark Pacific shearwater









First four photos are of Wedge-tailed Shearwaters for comparison. The first photo is by Juan Pablo Elizondo taken on April 2 on a Golfito, Costa Rica trip. The other three photos (with water background) were taken by Bruce MacTavish during his March 20 to April 16, 2008 trip off Costa Rica and Nicaragua.

The final five photos are of the mystery shearwater originally thought to be a Short-tailed Shearwater. Identification presently not known. All photos are of the same individual taken on March 29, 2008. The following are data for the sightings of similar birds. Photos and observations by Bruce MacTavish.

  • 1 on 21 March at about 25 km south of southern tip of Nicoya Peninsula.
  • 2 on 29 March. The attached photos were taken about 60 km offshore at N 8°59.95’, W 84°44.24’.
  • 4 on 30 March atN 8°46.121’, W 84°23.943’ about 50 km west of Osa Peninsula with 75 Wedge-tailed Shearwaters feeding around a group of 75 Common Dolphins.
  • 1 on 1 April at about 100 km SE of Osa Peninsula.
We are seeking comments from seabird experts (there is some discussion at http://groups.google.com/group/Seabird-News/browse_thread/thread/b34a6413fd338523?hl=en ) and will update when a decision is made about the identification of this bird.

Sharpbill and Nest at Tampanti NP

I had the priviledge to observe a Sharpbill (Oxyruncus cristatus) nest, mother, and 2 chicks (perhaps 3) in Tampanti National Park on June 21, 2008 with Elidier Vargas. Julio Sanchez and 6 others were also there taking pictures and field observations. Randal Ortega discovered the nest. It is the second known nest and the first to be documented in Central America.

The nest locations is up the road from the ranger station at N 09-44.931, W 083-47.119 (elevation approx. 1230 m).

Steely-vented Hummingbird (Amazilia saucerrottei) cerca de Guapiles

Tomando derecha a la restaurante Troucha en la pista cerca de Guapiles hacia la montañia unos 5-7 kilometros (450 metros sobre mar), observé un colibri Amazilia saucerrottei. El ave no tenia color rufous en la ala ni cola para eliminar el cyanura (blue-tailed HB) y el tzacatl (Rufous-tailed).

No veo mencionado en libro Skutch ni en libro Garrigues en esta area. Alguien lo ha visto alli?

saludos,

Black-Crowned Tityra at el Rodeo

Friday, May16th at 8:00 am, I spotted a male Black-crowned Tityra at La Universidad de la Paz (Tityra inquisitor) near the park entrance. I was not aware of this species in the Central Valley. Does anyone have a record of this species in Central Valley.

I also had a Pacific Screech Owl in my backyard on May 15th in Santa Ana.

Golfito Pelagic Birding Trip




Costa Rica Gateway organized a full day pelagic birding trip for 5 people (Kevin and Steven Easley, Magdalena Sánchez, Bart Browne and Jim Zook) out of Golfito on May 5, 2008. We went on the 28 ft. "Rosa Maria V" captained by Jay Belseski. The boat reached a point in open ocean about 45 km SW of Punta Matapalo (tip of the Osa Peninsula) before we turned back to port. Weather was fine with mild seas and no rain. The total number of birds was rather low but there was an excellent selection of species. The wonderful images shown above were taken by steady handed Steven Easley.
