Since its introduction, this dove has spread quickly across the North American continent. The northwestern spread of this non-native species made it to my yard a few years ago. In North America and the Caribbean, they are found mostly in suburban, urban, and agricultural areas where grain, roost, and nest sites are available.

There was a time when I thought each bird species had its own individual song. Then I found out that there was this vocalization called a ‘call,’ so I thought each bird species had its own individual song (but just the males) and individual call. Bird communication is a complex and evolving science. How do they know?

The Black Swift is considered a Species of Special Concern in California. Plus the fact that they only lay one egg per season which is incubated for about four weeks and the chicks don’t fledge for another fifty days gives you some notion as to why these birds are a Species of Special Concern.

Isla Rasa was declared a sanctuary in 1964, and egg-collecting and disturbance during the breeding season are discouraged. With the breeding colony concentrated on one small island this species is vulnerable to a catastrophic weather event. References: 1 Birds of North America Online , 2 BirdLife International.

For mankind to snatch away a species’ very existence is wrong on so many levels that I can’t begin to explain them. However, despite our best efforts to wipe them off the face of the earth, some of the more vulnerable species have managed to hang on. this species breeds.

The pair may have to compete for nesting cavities with several other species including native Tree Swallows and Violet-green Swallows, as well as non-native House Sparrows and European Starlings. The female alone incubates the usual 4 to 6 eggs for about two weeks beginning the day the last egg is laid. i Kamakawiwo?ole’s

Violet-green Swallows will nest solitarily or in colonies and in my experience seem much more mellow than other swallow species. The four to six eggs are white and unmarked.

Today, the species has all but disappeared east of the Mississippi River and has declined in western parts of its range, most likely caused by the expansion of the House Wren which destroys and removes their eggs from nest sites 1.

Horned Larks breed widely over North America, including up here in the High Arctic. For many North American bird enthusiasts, Common Ringed Plover ‘s are a bird they rarely, if ever, get to see.

Being a westerner — raised in California, and now living in western Mexico — I was perhaps most excited about the migratory birds that breed in eastern North America. This was only my fourth encounter with the species (all on the east side). Although, truth be told, this species does seem to be a rarity in Tabasco.)

I am only responding to my subjective impression of a single species’ appearance here; specifically, that of the Bronzed Cowbird. Instead, they lay their eggs in other species’ nests, and let those nest-making birds (often significantly smaller than the cowbirds) raise their young. Native versus invasive species?

Plus a few truly difficult species. Sure, it is an introduced species in Germany. But the Kentish Plover was sheltering its young under its body, and the Little Ringed Plover was incubating an egg — right in the middle of downtown Madrid! So seeing this beautiful (though common) European species was a special treat.

The White-headed Woodpecker is a non-migratory bird found in mixed coniferous forests dominated by pine trees in far western North America. Yah, another western species. White-headed Woodpeckers usually lay 4 to 5 eggs in a clutch and we’ve seen at least three different nestlings here now.

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. In this system, females mate and lay eggs with multiple males over the course of a breeding season, leaving males to incubate the eggs and raise the chicks.
