This is BirdNote.
In the American West, there are two species of phoebe that share the same expansive country. They鈥檙e both flycatchers, but they rarely compete for food because they鈥檝e evolved to occupy different habitats.
The Say鈥檚 Phoebe鈥檚 voice echoes off the rocks of almost any dry canyon west of the Rockies.
A small brown flycatcher with an orange belly, the Say鈥檚 Phoebe is named for Thomas Say, an early 19th Century explorer and naturalist. It prefers dry, open habitats ranging from tundra to desert 鈥� usually well away from trees or water. It鈥檚 just as happy nesting among stone carvings in an Aztec ruin in central Mexico as it is on a cliff face north of the Arctic Circle. No other North American flycatcher ranges nearly so far north.
The Black Phoebe is a close cousin to the Say鈥檚. But it鈥檚 nearly always hunting by a body of water. You鈥檒l find it alongside creeks, reservoirs, or even the tiniest pond in a back yard or garden.
Their voices set them apart, too. The brisk phrases of the Black Phoebe鈥檚 song鈥tanding in a sharp contrast to the plaintive refrain of the Say鈥檚 Phoebe.
With which it shares the American West.
