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.

Ackerman’s new book is about owls and owl research–the knowledge recently and currently being discovered through DNA analysis, new-tech tracking and monitoring, and old-fashioned fieldwork under the auspices of organizations like the Global Owl Project and the Owl Research Institute.

Oil begins to wash up on the beaches throughout May and June of 2010 May 6, 2010 Oil washes ashore on the Chandeleur Islands off the Louisiana coast, an important nesting and breeding area for many bird species. The babies that hatched from these eggs were released on Florida’s east coast.

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. It is hypothesized, for example, that nocturnal seabirds like the Bermuda Petrel eat bioluminescent prey.

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.

So these complex ecological interactions and systems must emerge as a result of individual behaviors, which also means to some extent, at levels within (below) the species we see interacting. New research on bluebirds helps address this question. One of the species that soon becomes abundant in fire disturbed habitats is the bluebird.

Shockingly, the Ashy-throated Parrotbill apparently is a species heavily hunted for bird fighting in Guizhou Province, China ( source ). Shame on the researchers. Some individuals even rejected their own eggs when they were in the minority. Some individuals even rejected their own eggs when they were in the minority.

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. One North American species I am very familiar with is the Cassin’s Auklet , which ranges from the end of the Aleutian Islands to California.

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?

Although designed as a field guide, it is a hefty book, 376 pages long, covering 336 species. Many species are dimorphic, with females looking different from males. Many species also differ with age. And, there are some odonate species that include andromorphs, females which look like the males. Yes, 675 photographs.

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.

But seriously, Science has a more interesting set of answers, and some recently published research on European Robins helps to examine this question in some detail. Here’s a short list of them: 1) Species recognition. Animals can assess species and sex with much more subtle cues. 2) Sex recognition.
