Breeding conditions:
|
The conditions last year were average, for the first time since 1998. Birds bred at average dates, hatching success was average and fledgling success too (although this latter variable is the least responsive to variation in weather, presumably because weather is less variable then too).
Ravens and gulls are important predators at Churchill. The temperature does seem to affect the intensity of search by predators, so lower mean temperatures result in greater predation pressure. Predation pressure on the Semipalmated Plover was average but in the past the success of one species in Churchill has been closely correlated with that of others.
