Mystery Bird: Dark chanting goshawk, Melierax metabates | GrrlScientist This African species closely resembles Saturday's mystery bird but it is actually a different species!Dark chanting goshawk, Melierax metabates, also known as the chanting goshawk, photographed at Serengeti National Park, northeastern Tanzania, Africa. Image: Dan Logen, 20 January 2010 (a glimpse through binoculars).Nikon D300, 600 mm lens with 1.4 extender, ISO 800, f/5.6, 1/500 sec.Question: This species closely resembles the bird I showed as yesterday's daily mystery bird, but it is actually a different species. What distinguishes these two species?Response: This is a dark chanting goshawk, Melierax metabates. It is distinguished from the eastern (pale) chanting goshawk, Melierax poliopterus, by two features: its cere and tarsi (legs) are red or bright pink, and its undertail coverts (alas, not visible in this picture) are barred.If you have bird images, video or mp3 files that you'd like to share with a large and appreciate audience, feel free to email them to me for consideration.GrrlScientistguardian.co.uk © Guardian News & Media Limited 2010 | Use of this content is subject to our Terms & Conditions | More Feeds guardian.co.uk |
