Costa Rica Bird Forum - Forum for Birdwatchers in Costa Rica: 2008

This amazing photo, taken by Cristian Gamboa, documents the first ever Gray-bellied Hawk (Accipiter poliogaster) recorded in Costa Rica. It is also a first for Central America. On June 26, 2008 Octavio Ruiz spotted the bird in a tree next to the suspension bridge over the Puerto Viejo River at the Orgnaization for Tropical Studies La Selva Biological Station in Puerto Viejo de Sarapiquí. He was accompanied by Yahaira Rojas, Kenneth Alfaro and Cristian Gamboa. All four of these lucky birders work the guides at La Selva.

Gray-bellied Hawk is a native raptor native to South America. The closest previously known records were from northern Colombia (although see the comments in the correspondence quoted below). It is a poorly known species and is rare throughout its range. The La Selva bird is a juvenile, and looks almost exactly like the mini-Ornate Hawk-Eagle. The adult is very similar to Bicolored Hawk, the biggest difference being that it has gray thighs rather than rufous thighs. In some older references authors have speculated that birds from the southern end of the species' range (Paraguay, and southern Brazil, Bolivia, and Argentina) maybe migratory. As this bird turned up in Costa Rica during the austral winter, it may have been a migrant that overshot its normal wintering grounds. However, there has been some recent discussion on this point and many experts from areas in the southern cone where Gray-bellied Hawk is found considering the species to be a year round resident there. So, migrant ?, vargrant ?, overlooked resident? We can only ponder the true nature of this exceptional bird.

Hi Bill! Yes, I agree, undboubtedly to Gray-bellied Hawk. Look how the dark mallar stripe touches the black cap behind the eye - you do not seed this in Ornate Hawk-eagle, where the rufous clearly separates the cap and the mallar stripe.Look for comparison at: http: //farm1.static .flickr.com / 34 / 72062929_f61e76f379.jpg? V = 0Also the 'barring' on the median portion of the belly is more 'spotty' (unlike in OHE) .Great news! I saw one older imature (thighs still barred, but rest like adult) in Darien, Panama in 2005, but since I took in the photos and the bird was 'out of range' I usually do not mention It.
Thank you again.

I have been faithful and unfaithful, I myself have lied some time, but the record of being hooked on the doors I have, clearly. I hated it when I put frying pans in a suitcase that I had given him and I wondered if he could take this pot or towel.

Hi Sergio, I think this is a juvenile A. poliogastor
If so, it is Way out of range in Costa Rica.
