This is bird note.

Hidden in a tree's dense leaves, a tiny Kentucky warbler sings its heart out.

This shy bird's hard to see, but when it finally pops into view, it is well worth the wait.

Bright yellow below, with a dark green back. The Kentucky

Warbler has long black sideburns on its yellow face. Sideburns that some birders say remind

them of Elvis. Kentucky Warbler's nest in forested regions in much of the east, preferring

woodlands with a dense understory,

often near streams or other wetlands. They winter in Central America, where they've adapted

their hunting technique to follow swarms of army ants and snatch the insects the ants

flush from cover.

But these charismatic little birds can use our help.

As their forest habitat shrinks, it's easier for brown-headed cowbirds to find and parasitize the Kentucky warbler's nests.

While migrating, they're easy prey for domestic cats, so keeping cats indoors can save many

warblers. And buying products like shade-grown coffee can help keep their tropical winter habitat

in good shape, because we want to make sure that warbler, with the sexy sideburns, keeps on singing.
