This Morning Outside

Singing his tiny lisp of a song this morning at the top of his lungs, the Henslow's sparrow doesn't trust just one twig. He spreads the risk between a couple of far-spaced footholds.

Henslow's sparrows depend on grasslands, as that's the only place they can nest. Good reason for keeping some land in grasses, especially native grasses.

Listen to the song
of Henslow's sparrow

I recorded the song of a Henslow's sparrow in Jefferson County, Iowa, in the month of June. I processed the recording using Raven Lite software.

Here it is at normal speed, just as whispered tslick.

And here is the same song again, played at 1/10 speed. Slowing it down like this allows our human brains to hear detail that otherwise is too fast for us.

(If you don't hear six or seven notes, give it a few seconds and try again. It may take a while to load the sound.)

Best-Value Binoc

We love the new Vortex Viper HD 8x42 binocular.

Vortex Viper HDIt's a high-quality binocular, one that bears comparison to the highest-priced binoculars in the world. Yet its price is in reach for serious but budget-minded birders.
