Recent Birds at Rio Bosque
Water deliveries to the park from the Roberto Bustamante Wastewater Treatment Plant ended on 2 February. The levels in the wetland cells and the old river channel are dropping.
For the moment, ducks continue to be present in good numbers. Northern Shoveler, Gadwall, American Wigeon, Mallard, Mexican Duck, Northern Pintail and Green-winged Teal predominate. Cinnamon Teal are present in small numbers.
Our pair of White-tailed Kites, first seen 25 May, has now been present for over 8 months..
Burrowing Owl activity has been slow, but owls have been seen in recent weeks at 4 different burrow sites.
American Crows and Chihuahuan Ravens began returning to Rio Bosque in mid-October. Their numbers swelled rapidly, and over 2,000 are now returning each day near sunset to roost in and near the park.
