Collared Forest-Falcon Micrastur semitorquatus
This species is found along both slopes, though is not found in the higher parts of the central highlands. Collared Forest-Falcons have a very distinctive falling Oww call, that is often heard at dawn and dusk. Despite hearing them regularly, I have still only ever seen one in the region (at La Montañona). It has always surprised me how few I see. For example, I hear them regularly at Perquin, where I am often in the field from dawn to dusk, but I have still never seen one there. I have also heard them at Barra de Santiago, Nancuchiname and Walter Deininger, which are all in the Pacific lowlands. I have not come across them in Guatemala and my only records from Honduras are from Las Marias.
