Fledgeling Spot-crowned Barbets at Achiote, a report by Bill Adsett

Imagen
Mariló Castro had been monitoring daily for months an active Spot-crowned Barbet nest in a hole in a dead trunk behind CEASPA's El Tucán Community Center at Achiote, Colón. On June 9 she and I (visiting for the day) were alarmed to find that the nest had been ripped open all the way down one side during the night or extremely early in the morning, and the adult and young birds were nowhere to be found. It was feared a predator had taken them. But then a barbet was heard vocalising nearby and we were relieved to find both parents and two fledglings safe and sound in a fruiting tree. One fledgling was in male plumage, the other in female plumage (is this unusual?). The male parent was feeding the female fledgling (and vocalising) and the female parent was feeding the male fledgling. Despite having left the nest for the first time only a few hours previously, both young birds were jumping from branch to branch and flying strongly and proficiently. The young male had been seen befor...

Cattle Tyrants at Biomuseo

The pair of Cattle Tyrants that have taken up residence in the Biomuseo parking lot spent all day yesterday happily confronting their reflections on every windshield in the area, and we have videographic evidence.

Biomuseo Cattle Tyrants: still here

A pair of Cattle Tyrants have spent all afternoon on the lawns at the southern side of the Biomuseo, at the very tip of the Amador Peninsula. Here is one admiring Frank Gehry's architectural masterpiece.

Capuchinos Tricolor en Alanje, un reporte por Boris Sanjur

Imagen
El 30 de mayo, cerca de las 6 de la tarde, cuando realizaba observaciones para su proyecto final en la comunidad de Las Moras, Alanje, Chiriquí, la estudiante de Ciencias Ambientales y Recursos Naturales de la UNACHI, Maryelis Ríos y su hermano Eloy Sánchez observaron un grupo de aves (5) sobre unos arbustos. Envío las fotos más claras que me mostraron donde parecen ser Capuchinos Tricolor ( Lonchura malacca ).  Tal vez una expansión de Costa Rica.  Como nos comentó Daniel Mclaren es muy probable que hayan ampliado su rango ya que él ha observado grupos de 30 ó 40 individuos en Laurel y Corredores, muy cerca de la frontera panameña.
