The Brown Pelican occurs in both the Pacific and Atlantic coasts of North America and northern South America. Analyses of stomach content of dead pelicans during a die-off found that their digestive tracts were either empty or contained fish the pelicans don’t normally eat. Brown Pelicans in non-breeding plumage.

A distribution map shows areas in South America where the species has been found, with letters and dotted lines indicating subspecies areas, red dots showing where the type specimen was found, and X’s denoting questionable sightings. They are, of course, of antpittas building or incubating eggs on a nest. Organization.

In North America and the Caribbean, they are found mostly in suburban, urban, and agricultural areas where grain, roost, and nest sites are available. They usually lay two eggs per clutch and most often, successive clutches will be laid while adults are still attending fledglings! This next map is data from 2007 through 2008.

Whatever content can be used is absorbed from within the digestive tract into the blood in the form of molecules. Whatever food content cannot be used is thrown out through defecation. Or picture yourself as a bird fetus within an egg. Drinking and peeing through the egg shell? Not a sustainable concept of development.

The analysis of Python stomach contents indicates that they eat mammals, as small as mice, and as large as a fully grown deer. Some of these snakes had evidence of birds in their stomachs and some were gravid with up 55 eggs nearly ready to be laid.

The where and how of egg laying and larva emergence is briefly treated, with page references to larval drawings at the back of the book. And, to be fair, with the small number of species located in Great Britain and Ireland, there is far less confusion than in North America. In fact, visuals dominate all the introductory sections.

Often, as I have been investigating the contents of a nest by making a small hole in the side, the parent birds have come right to the nest, where they immediately begin to repair the damage even before my departure!”. The artwork in my edition of Birds of Northern South America is much more intense in color.

What is amazing is that each of these three books is very different in content and tone. Still, I can’t help thinking that there is some parallel between the mass slaughter of the Passenger Pigeon in 19th-century North America and the mass slaughter of songbirds in southern European countries today. How many times did it nest?
