It is not particularly big but has a reported 430 bird species including migrants, though during my short stay it seems I missed most of the key attractions among them. Poor researchers Nicola Coumi and Rob Slotow failed to find anything particularly interesting about vigilance in Bronze Mannikin groups.

An associated issue is that the Belize and Costa Rica guides share many of the same descriptions of species, written by Howell. Similarly, descriptions of species repeated across volumes do not lose their accuracy with each publication. Other species are splits and lumped and have had their names changed. Why are these issues?

Its species name graydoni is in honor of Philip Newenham Graydon (1864-1940), a British planter in Sabah. Why that makes Mr. Graydon worthy of having a bird species named after him is a mystery to me.

And the term is ‘non-reversed size dimorphism.’).

The book is divided into three parts: “Introduction,” “Avifaunal Overview,” and “Species Accounts.” The authors’ detailed delineation of problems with the accuracy of NYC breeding bird surveys or with the limits of historical writings may test a reader’s patience. Most birders will go straight to the “Species Accounts.”

In recent years Indonesia has been competing with the Andes as the region giving rise to the biggest number of undescribed bird species (naturally, all of them endemics).

Third, observing and photographing breeding birds and their young have become acts of ethical confusion as birders, photographers, and organizational representatives debate the impact of our human presence on the nesting process.

Such programs are somewhat inefficient anyway – in one study , the breeding success of wild male pheasants was 2-5 times higher than for hand-reared and released ones while for females, hand-reared birds were 3 times as vulnerable to predation as the wild ones.

The feature distinguishes birds from other species; All birds have them, no other species do.
