The juvenile Pied Oystercatcher gives you a glimpse into its development when it stretches a wing out and when it stands close to its parents for size comparison. Pied Oystercatchers are not a species that we observe flying very often at all. They prefer to walk away from you to lead you away from eggs, chicks or their territory.

The obvious choice was the Mallard , that plucky familiar northern hemisphere species that is the father of the even more familiar domesticated duck. In fact, as the species was quickly identified as as creating hybrids with Grey Ducks, the opinion was by the 1920s that the species shouldn’t be released further.

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. Some people love books like that. Peregrine Falcon nests.

Horned Larks breed widely over North America, including up here in the High Arctic. Here they are a common breeding bird, one of our two species that migrate from here to Europe and then south. At the same time (and sometime the same location) we have Semipalmated Plovers breeding, which makes identification a challenge.

Clicking on the map will take you to an explanation of this important biome, including its climate and its plant and animal species. About three billion birds fly north to the Boreal Forest each spring to build nests and lay eggs. There are nearly 100 species of which 50% or more of the entire population breeds in the Boreal Forest.

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. One of Britain’s recent colonisers the Mediterranean Gull begins to arrive in bigger numbers every year as post-breeding dispersal takes hold.

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.
