Colombia has one of the longest lists of bird species recorded within its borders, so its modest output of bird stamps
is to be commended when compared with the number of stamps recently issued by some countries.
After a 5-year gap, Colombia's latest stamp with birds celebrates Los Katios National Park which is in the far north-west of the country, bordering Panama. The park comprises low hills, forests and humid plains. An exceptional biological diversity is found there, and it is home to many threatened animal species, as well as many endemic plants.
A good selection of wildlife is shown on the stamp, including the only South American species of bear - Spectacled bear (Tremarctos ornatus). Of the four species of bird on the stamp, three are fairly easy to identify. The Northern Screamer (Chauna chavaria) is new for my collection, and the best image I could find on the web is here. There is also a sheet of stamps from Grenada Grenadines which features this species. The flying bird of prey shows the chestnut nape and heavily barred underparts which is typical of Ornate Hawk-Eagle (Spizaetus ornatus). The macaws perched in the foreground are Red-and-green Macaw (Ara chloropterus).
This just leaves the bird flying over the macaws, enlarged above. I cannot find an exact match for this one, but if it did not have such long legs, it would be most like Black-crowned Night-Heron (Nycticorax nycticorax).
