At the height of summer, deserts reach scorching temperatures and water is scarce. But as BirdNote®’s Michael Stein reports, desert birds are well-adapted to the intense heat and dryness.
CURWOOD: We are in the hot, dog days of summer, here in the northern hemisphere but as BirdNote’s Michael Stein reports for desert birds the searing heat is no problem.
What Do Desert Birds Drink?
[Desert atmosphere with insect buzz and call of Gambel’s Quail]
In the desert Southwest, summer temperatures sizzle, rising well over 100 degrees. And in some parts of the desert, there is not a drop of water for miles.
Yet some birds thrive in this scorching landscape. Here a Black-throated Sparrow sings from a thorn scrub. [song of Black-throated Sparrow] Now, a Cactus Wren announces itself atop a barrel cactus. [Cactus Wren song] And neither will be flying miles every day to the nearest source of water. So how do they survive?
Birds, like all animals, perish without water. Desert birds, however, make the most of very little. They tuck into the shade in the heat of the day, so they won’t lose water in panting. They have extremely efficient kidneys, so they excrete almost no liquid. And they obtain moisture from foods, like nectar and fruit as well as insects and other prey. [Insect sounds and Black-throated Sparrow song] Even when eating primarily seeds, Black-throated Sparrows are able to extract enough water from this dry food that they may never need to take a drink.
[Thunder storm sounds]
Still, when that next late summer thunderstorm arrives, you have to think those temporary puddles are going to look mighty refreshing.
