BirdLife International believes that this might be maximum population the species can reach, as it seems to completely saturate its range.

I like observing them, reading about them, grappling with species and subspecies identification, and even—on a good day—talking about sparrow taxonomy. Peterson Reference Guide to Sparrows of North America covers 61 species of the New World sparrow family Passerellidae that breed in Canada, the United States, and northern Mexico.

Did I dare dip my toe into this catalog of tantalizing species? Phillipps’ Field Guide (I’ll be using this shortened form of the title) covers 673 avian species, including 59 endemics, and 53 species that have not been documented yet for the area but which may show up in the next few years. Now, I’m not so sure.

The story of the cahow, a “Lazurus species” that was thought to be extinct for over 300 years and then discovered to be breeding on a tiny remote island in Bermuda, is part of modern birding legend. In 1951, there were 18 breeding pairs of cahows discovered on three tiny islands.

Even the Latin species name soror (“sister”) indicates the similarity to another pitta species (blue-naped). The eBird description of the Small Niltava starts with the surprisingly dull statement that “size distinguishes this species from other niltavas” Who would have thought.

” Writing about owls means writing about roughly 250 species (I counted 245 on the 2022 Clements spreadsheet, but I might have missed a few, and we all know that each classification system is different). The chapters on courtship and breeding and roosting and migration are the longest, which isn’t surprising.

In total, there are eight species of hornbills in Borneo – the best place to see them seems to be the Kinabatagan River area (also known as Sukau). Another paper reviews information on Oriental Pied Hornbills raiding the nests of various bird species in Singapore and even pet bird cages.

A few families have a small number of eggs in the clutches, like gulls or cormorants. Others, like the petrels and some of the auks, will lay a single egg per breeding attempt. The investment placed in each clutch bur seabirds is so great that only one breeding attempt can be seen to completion each year.

Basically, this species is so dimwitted, it doesn’t know how to survive. Because, Pink Pigeons are not capable of doing the tasks required to create and bring up children of the species. These endangered birds have trouble producing a fertilized egg and, even worse, they don’t even know how to build a nest so the egg survives?

The family has about 37 species, but that includes several fulvettas – only 21 of the species have “parrotbill” in their names (and frankly, the bills of fulvettas do not look like those of parrots at all). A paper on breeding of the species was actually researched right here at Wawushan.

One of the more interesting aspects (in my opinion) of breeding in birds is their mating strategy. The most common mating strategy in birds is social monogamy, found in roughly 92% of birds species in the world (Jenni 1974, Owens 2002). of all bird species, is polyandry. Polyandry is found mostly in shorebirds (e.g.

It is almost as though the eagles, and other territorial carnivores, have spaced themselves out on the landscape just right so that they don’t overuse their food resources, so that they, the eagles, can continue to do their thing without threat of eating up their own food supply. The eggs or chicks would not survive.
