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.

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.

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. They prefer to walk away from you to lead you away from eggs, chicks or their territory. We would not expect it to breed for several years yet.

Griffon Vultures have a long breeding season. The chicks need six months to develop so the adults lay their eggs in January. Isn’t it a bit late to breed? Why bother with such a risky journey if you aren’t going to breed? In comparison, over 15 thousand Griffons make the same crossing each season.

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.

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.

Using ministerial connections he obtained 100 mallard eggs from the US and began to breed and distribute them. It’s a very unfair comparison, but it can be hard to explain, in layman’s terms, what is being lost. Female Mallard, photo by Corey.
