Accipiter velox
Oct. 18 El Batel, 5,00 ft., Sinaloa.
A male was collected in a densely forested draw, where it had been chasing a acorn-
storng woodpecker. Another, a female,
was obtained by Leopold on Oct. 17 along
the ridge above camp. He also observed
several others flying along the ridge, apparently
in migration.
