Naturalist notes
By late May, Mexican free-tailed bats return to the evening sky in the Lower Rio Grande Valley, emerging at dusk to feed on flying insects above the canal banks and resacas.
Granjeno shrubs set small orange-red fruit along brushy edges in late spring, drawing curve-billed thrashers and other birds that forage low in the thornscrub.
