Großer Pfeifentyrann

Bestimmung

This species is slightly longer than the olive-sided flycatcher. The adult greater pewee is the largest breeding Contopus flycatcher to breed in the U.S. It is a dull gray-brown bird all over with some birds that have a buff wash on the breast. They have indistinct wingbars and a very distinct crest. The lower mandible is bright orange and that is an easy way to distinguish them from olive-sided flycatchers in eastern Arizona and west central New Mexico. They are 8 inches (20 cm) long, have a 13 inches (33 cm) wingspan and weigh 1 oz (28 g).

Verhalten

These birds love to stay high in trees scanning for insects. They sally and hawk insects from their high perches. The greater pewee defends its nesting grounds aggressively. They will attack hawks, jays and squirrels. Their diet consists of insects and maybe berries in cooler months. Their song is a whistled five syllables: deelip deeree! ah or famously known as jose maria. The opening deelip is repeated several times before the rest of the song. It also gives pip calls like the olive-sided flycatcher.
