Predators that rely on lemmings, like the Snowy Owl , took advantage of the bounty and had great breeding success, raising large broods which, after the lemming population crashes, dispersed far and wide. And while I haven’t made it over their yet I hope to before they disperse into breeding territories.

Two-thirds of the world’s population breeds colonially on Greek islands. Unlike other falcons, they do not breed in spring, but in late summer, to exploit the abundance of songbirds and pick up those first-time (and last-time) migrants from the sky.

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 Ontario breeding population of this grosbeak is stable. It is reliably identified by its larger size, darker and browner colour, longer/thicker bill and longer tail in direct comparison to “Southern” Common Redpolls (nominate flammea subspecies). Highest breeding densities are found in areas with spruce budworm outbreaks.
