Xenornis

A principios de esta semana visité la provincia de Darién con Euclides Campos, Dave Klauber y Margot Ramos.   En la tarde de 20 de Julio visitamos un propiedad privada con arrozales cerca de Aligandí. Poco despues de llegar encontramos un  Agilucho de Azara  (Long-winged Harrier) de fase oscura, y lo observamos volar y cazar durante unos 10 minutos. Pude tomar algunos fotos de este ave hermosa. Un poco despues vimos otro Aguilucho de Azara —esta vez un individuo de fase clara. Nuestra increíble tarde continuó cuando escuchamos un  Rascón Moteado (Spotted Rail). Tuvimos breves vistas de esta ave difícil de ver en el borde de un arrozal, pero finalmente pudimos obtener vistas más claras —aunque demasiado rápidas para obtener un foto [ eBird ]. A la mañana siguiente volvimos al área y volvimos a ver el Aguilucho de Azara de fase oscura. Otras aves raras que vimos en el área incluyeron a varios Tordos Capuchiamarillos (Yellow-hooded Blackbird) y un Halcón Aplomado ...

Venicio Wilson found this Long-winged Harrier at Juan Hombrón on the morning of Saturday, March 21. Also present was a male Northern Harrier and two male Painted Buntings.

Osvaldo Quintero photographed this dark-phase Long-winged Harrier  at the entrance to Mono Titi Road at Parque Metropolitano, this morning at 7:15.

Rafael Luck sent in his photos of the Long-winged Harrier his group (which included Venicio Wilson, Osvaldo Quintero and Jan Axel Cubilla) found in Juan Hombrón yesterday. Comparing the photos with the poor illustrations of the species in South American field guides, and having never seen the species ever, I'd say this is a young dark morph adult (fide the few pale streaks in the underparts). They also had this American Golden-Plover at the same location and later encountered a Northern Harrier in El Coco, for comparison.

This Long-winged Harrier , apparently a dark-phase adult, was photographed yesterday at Juan Hombrón, Coclé: about 100 km west of the westernmost previous records from Tocumen Marsh.  En estos momentos estamos recibiendo reportes de que en la carretera que va a Juan Hombrón, en el área de arrozales, se está observando un Long-winged Harrier. Otras aves vistas incluyen varios Pectoral Sandpipers y un American Golden-Plover . Observadores: Beny Wilson Altamiranda, Rafael Luck, Osvaldo Quintero y Jan Axel Cubilla Rodríguez. More details to come.

As promised, Alfred Raab sent in photos of the Long-winged Harrier seen by him, Mark and Joanie Hubinger an Ken Allaire on April 11, 2010 . From the photos it looks like a normal-morph adult, perhaps a male (although the underparts in the last photo look pretty buffy).

Alfred Raab, Marc and Joanie Hubsinger and I found a Long-winged Harrier on Sunday at about 1:00, completely by coincidence as we had not read Kilo's post. Alfred and Marc both obtained excellent photo documentation, which will be posted at their earliest opportunity. But our bird was definitely a light-morph male, not a dark-morph as Kilo described— our photos prove this conclusively. We also got close to a couple of rice fields and I had an all-too-brief look at a Spotted Rail in a small patch of irrigated rice.

Euclides Campos and Alex Guevara tried to visit the now off-limits Tocumen Marsh this morning; access was denied, as is often the case of late. Still, they stopped at a lookout over the rice fields and, using a spotting scope, identified a distant all-black harrier with gray primaries as a dark morph adult male Long-winged Harrier . Alas, the rice fields were too far off to try to spot any rails.

Durante los días patrios decidí ir con unos amigos a visitar el Real y Rancho Frío. El jueves 5 de noviembre, fui al airstrip en la mañana donde me tropecé con este harrier. Este individuo era bien oscuro con algunas rayas blancas por debajo. De acuerdo a la literatura, el juvenil dark morph Long-winged Harrier es todo dark brown y poseen rufous thighs. En una de las fotos se puede ver algo los rufous thighs. Los juveniles northern harrier son oscuros en el chest y luego twany el resto. En rancho frío vimos Double-banded Graytail, Wing-banded Antbird, Yellow-backed Tanager, Scarlet-browed Tanager, Sapayoa, Black-and-white Hawk-Eagle, Ornate Hawk-Eagle, Plumbeous Hawk y Tawny-faced Quail.

The Canopy Tower's Carlos Bethancourt saw the Tocumen Marsh Long-winged Harrier while leading a small group. This time the bird was working the ricefields on the road out to the beach. Also seen was a single Orange-crowned Oriole.

The high point of the PAS fieldtrip to Tocumen Marsh was the third report of Long-winged Harrier for Panama. The bird was working the ricefields around the far reaches of the main road, taking a left at the dike road. Report by Jan Axel Cubilla, photos by Karl Kaufmann. Lo que vimos fue un típico Circus con alas largas y estrechas, cola larga y vuelo bajo con cernidas ocasionales. De pardo a pardo oscuro por encima con obvia rabadilla blanca estrecha (como una franja) y cola con varias (minimo tres) franjas pálidas (blancuzcas-anteadas). Por arriba se hacia obvio puntas negras de las primarias y un panel más claro formado por las primarias. Por debajo de las alas fue difícil discernir el color... parecía oscura, pero las fotos hacen notar que era pálido. Partes ventrales de un color blanco cremoso, con cuello ventral, pecho superior y cara negra contrastantes con marcas blancas (superciliares?). Patas largas de un color amarillo-naranja prominente. Lo observamos primero un poco antes d...

aúl Arias also forwarded the following report by Allen Chartier. This would be the second Panama sighting of Long-winged Harrier: While waiting for an airplane to arrive from La Palma to take us on a much-delayed flight to Panama City, a largish dark raptor flew low over the canegrass at the north (?) end of the runway about 30 yards away. As viewed through Zeiss 10 x 42 binoculars, the bird had an all-black head and underparts. The upper and under-wing coverts were all black as was the back. The face showed faintly, but clearly, a suggestion of facial disks (characteristic of harriers). The bill was dark and the color of the cere was not determined as it wasn’t particularly conspicuous. The remiges were checkered (or barred) with black and medium gray both above and below. The tail had 5-7 black bars with the same medium gray between. The rump and upper tail coverts were black except for a very narrow white edge on the distal upper tail coverts. The bird was shaped very much like a No...
