There were so many potential titles for this post, from some of our greatest songwriters (StingRobert Smith, heck even Leonard Cohen). But at the end of the day, none of them can compare to the sound of a male Greater Sage-Grouse in love, almost alien in its ardor. And these dudes’ vocalizations and “sonations” increase in intensity when a lady Sage-Grouse is present—which, in turn, seems to increase the male’s mating success.

That’s the finding of a study recently published in The Auk. Researchers from Auburn University and the University of California–Davis examined the non-vocal noises that Greater Sage-grouse make with just their feathers and wings. (The researchers termed these sounds “mechanical swishing.”)

The upshot of the study is that the most successful mating males were keen observers of local social dynamics. They tended to bump up the frequency range and intensity of their swishing displays when females approached. Those that did were more likely to get some action.

All of which brings to mind, to me at least, another male courtship display that grows more frenetic and fervent when females are near. (Not that it ever really works for those guys)

The lowly Red-winged Blackbirds in suburban New York triggered Meredith Mann's interest in birds. Five years later, she's explored some of the the USA's coolest hotspots, from Plum Island in Massachusetts to the Magic Hedge in Chicago to the deserts of Fallon, Nevada. She recently migrated from the Windy City (where she proudly served as a Chicago Bird Collision Monitor, rescuing migrants from skyscrapers and sidewalks) to Philadelphia, where she plans to find new editing and writing gigs; keep up her cool-finds chronicle, Blog5B; and discover which cheesesteak really is the best. And she will accept any and all invitations to bird Cape May, NJ.
