Food: Ivory-billed woodpeckers could be of economic importance except for their small numbers (Greenway 1958). The woodboring larvae making up a third of their diet (Beal 1911) are injurious to trees (Pearson 1936), and are most abundant in areas where recently dead and dying trees are numerous because of flooding, fire, insect attacks, or storms. The birds stay as long as there are abundant larvae (Dennis 1967). They also eat fruit of magnolia and pecan trees (Beal 1911).
Sulphur-bellied flycatcher
Myiodynastes luteiventris
L 6¾″
Habitat: The sulphur-bellied flycatcher is a common occupant of riparian habitat with sycamore trees in deep canyons from 5,000 to 7,500 feet elevation in the Huachuca Mountains of Arizona.
Nest: Invariably the nest of this species, made from leaf stems (Peterson 1961), is built in a natural cavity in a large sycamore at a height between 20 and 50 feet above the ground. The cavity normally is a knothole where a large branch has broken off (Bent 1942). At least one member of each pair may return to the same nest site each year.
Food: Little information has been published on the food habits of this flycatcher, but insects caught in the air are undoubtedly the major items. Apparently small fruits and berries also are eaten (Bent 1942).
