It breeds across much of NorthAmerica, is present year-round in the Caribbean, northern Central America, and the west coast of northern South America, and in winter is found across the rest of Central America. The Killdeer is a wide-ranging plover.
A breeding bird atlas is a special kind of book. For ornithologists, it is the documentation of a multi-year project designed to record the distribution and abundance of birds in a specific area (in NorthAmerica, usually a state or a province), utilizing a mapping method involving blocks and grids.
Most of the Osprey breeding in NorthAmerica are migratory, only Florida, the Caribbean and Baja California host non-migratory breeders 1. In migratory populations males usually arrive to breeding grounds a few days before the females and look for nest sites. This pair copulated several times while I was observing.
All New World Quail are highly gregarious, typically found in coveys or flocks except during breeding season. In California, coveys break up and pairs begin forming in February or March, followed by nest building and egg laying in May or June. She will usually lay 12 to 17 eggs, averaging five per week 1 , before beginning incubation.
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. And of eggs and nests and birds on nests. Cedar Waxwings exchange berries, carry nesting material, eggs.
All four major flyways in NorthAmerica — the aerial migration routes traveled by billions of birds each year — converge in one spot in Canada’s boreal forest, the Peace-Athabasca Delta in northeastern Alberta. About three billion birds fly north to the Boreal Forest each spring to build nests and lay eggs.
The Bank Swallow ( Riparia riparia ) is NorthAmerica’s smallest swallow. These birds have lost more than half their global population, and the 33 species combined have lost hundreds of millions of breeding individuals in just the past 40 years. References: 1 Birds of NorthAmerica Online.
The nickel was placed in the nest for the photo to show me the size of the egg for identification purposes, then removed. Even though the female lays only two eggs per nest attempt, they enjoy a protracted breeding season in which multiple nesting attempts can occur every 30 days, and in Southern locations, nearly year round.
Heermann’s Gulls form large breeding colonies on arid islands in the Gulf of California, Mexico, from March through July. The largest colony exists on Isla Raza, where an estimated 90–95% of the total world population breeds 1. This photo by Basar from Wikipedia Commons shows the adult in breeding plumage. www.youtube.com/watch?v=FUBX_tlHySc.
I think most of us in NorthAmerica have come to the somewhat disappointing conclusion that fall migration is pretty much finished for the year. We get to see a lot of them around here, and familiarity breeds, not contempt certainly, but perhaps apathy. You’re done. Look at those bright legs!
Horned Larks breed widely over NorthAmerica, 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. Here they are a common breeding bird, one of our two species that migrate from here to Europe and then south.
Even though the overall breeding range remains largely unchanged from that in the 1940′s, the entire coastal population has been in recent severe decline. The ecological requirements for Black Swifts to breed restrict them to a very limited supply of nesting locations. Photo from Wikipedia Commons taken by Terry Gray.
The featured image above shows a female incubating eggs from my first resident breeding pair back in 2007. The four to six eggs are white and unmarked. It’s not as clear as the photo of the eggs above but I did not want to disturb the female as she was circling the nest to resume her duties.
Within a group, 1–7 male co-breeders compete for matings with 1–3 joint-nesting females who lay their eggs in the same nest cavity. Groups may also contain up to 10 male and female non-breeding helpers, usually offspring of the group produced in prior years 1. References: 1 Birds of NorthAmerica Online a.
” The report continues: “Following the breeding season, most tricolors are found in the Sacramento Valley where they aggregate with red-winged and other blackbird species and feed, often in large flocks, on ripening rice. References: 1 Birds of NorthAmerica Online.
Brown Pelicans in non-breeding plumage. The Brown Pelican occurs in both the Pacific and Atlantic coasts of NorthAmerica and northern South America. Both are the only Pelican in their non-overlapping breeding grounds. Peruvian Pelican in non-breeding plumage. Brown Pelican in Breeding Plumage.
In NorthAmerica and the Caribbean, they are found mostly in suburban, urban, and agricultural areas where grain, roost, and nest sites are available. In warm climates they can breed year round. They usually lay two eggs per clutch and most often, successive clutches will be laid while adults are still attending fledglings!
Kirtland’s Warbler is a classic niche species; they breed in only very specific conditions, which occur in only a very specific area. this species breeds. Short-tailed Albatross was thought to be, at one time, the most abundant species of albatross in the North Pacific. Santa Cruz Island, CA. Somebody won a Nobel Prize.
This entire cycle begins in early Spring when Western Bluebirds pair up for breeding.

State and Federal Agencies feared that if these two large constrictor snakes are allowed to breed they would produce a hybrid super-python. Photo Credit: Invasive and Exotic Species of NorthAmerica (www.invasive.org). Rock Python. Photo Credits: Samuel Wright.
Now, more than ever, they are an iconic piece of the birding landscape, for David Sibley’s “ The Sibley Field Guide to to Birds of Eastern NorthAmerica ,” features none other than an American Goldfinch on the cover! Unlike many other songbirds, these goldfinches subsist entirely on a vegetarian, seed-based diet.
Especially the bird breeding season, which passes by at the blink of an eye. This pair first appeared four years ago, and are amongst the most northerly known breeding Pacific Loons in NorthAmerica. However the night before last all hope was lost, the egg now gone, the birds still on the lake.

The other sub-species, Calidris canutus roselaari , migrates along the Pacific Coast and breeds in Alaska and the Wrangel Island in Russia.
Cliff Swallows migrate to NorthAmerica from their wintering grounds in South America to nest in large colonies, sometimes numbering in the thousands. In addition to their homing tendency, breeding swallows are attracted to old nests. Under suitable conditions, a nest is quite durable and can be used in successive years.
Instead, they lay their eggs in other species’ nests, and let those nest-making birds (often significantly smaller than the cowbirds) raise their young. So that is a negative mark on both their records. In contrast, the Brown-headed Cowbird is a same-continent invasive species. This is a rather typical group size for Bronzed Cowbirds.
July, as all northern hemisphere birders appreciate, is the month when the egg timer flips and everything starts pouring back out again in a steady stream south.

The length of each bird species account varies, depending on whether the bird is native or a “visitor” (the book’s term for migrant) or vagrant, breeding or non breeding. They breed in dense colonies, incubate their single egg on the feet, and take more than a year to fledge a chick.
The shape of the Osprey nest changes during the breeding cycle. Pairs average 59 successful copulations per clutch, starting 14 days before, and peaking a few days before, the start of egg-laying 1. Pairs copulate most often in early morning, at the same time as egg-laying 1. References: 1 Birds of NorthAmerica Online.
A lovely looking and distinctive sounding bird (so they say, I sadly have not seen one…yet), the Kirtland’s Warbler can only be found during its breeding season in Jack Pine forests 5 to 20 years old in the northern Lower Peninsula of Michigan. William Rapai (pictured left) is a newspaper reporter and editor who is clearly also a birder.
Still, I can’t help thinking that there is some parallel between the mass slaughter of the Passenger Pigeon in 19th-century NorthAmerica and the mass slaughter of songbirds in southern European countries today. How many eggs did a pigeon lay? Or the destruction of the forests, food source and breeding grounds.
So, I was very excited when I heard that Rick Wright was writing a book about sparrows, the first treatment of North American sparrows since 2001, possibly the first book about sparrows of NorthAmerica, depending on your definition of that geographic area. They’re all birds of NorthAmerica! Mexico border.
One of the more interesting aspects (in my opinion) of breeding in birds is their mating strategy. 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. of all bird species, is polyandry. 1996, Nakamura 1998).

Sexes are highly dimorphic.
It covers 63 odonate species: 44 breeding species (19 damselfly, 25 dragonfly), and, in a second part of the Species Accounts, 19 vagrant, potential vagrant and former breeding species (5 damselfly, 14 dragonfly).

Let us for once judge a book by its cover, and take a thorough look at a Black-headed Gull in breeding plumage. How do I know of their Gothic moods when they have hidden them so well in an egg-white shell of conformity? Are you quite sure that sentence should not include &# their appearance &# and “ apparently “?
As strange as it may seem, sexual dimorphism and breeding behavior are reversed in these species. As a matter of fact, according to Birds of NorthAmerica Online , “Courtship displays with copulation include bowing and upright postures and vocalizations by both sexes, but are usually initiated by females.
It made us reach for our field guide for NorthAmerica, but that really does not compare to the real thing. May you all see a lot more wood-warblers in the weeks to come and we will have to get back to America to see some more… oh, and update the field guide!!
