Brown Jay
Brown Jay
Psilorhinus morio
At a Glance
At dawn in the woods of south Texas, a shrill, explosive pyow! pyow! announces a flock of Brown Jays. These big birds, much larger than our other jays, are almost always in flocks, and their calls can be heard for more than a quarter of a mile; but they can be surprisingly inconspicuous when they stop calling and slip away through the trees. Common in Mexico, Brown Jays crossed into Texas in the 1970s; they are still very scarce and local there, found only on a stretch of the Rio Grande below Falcon Dam.
