Recent Birds at Rio Bosque
Water deliveries to the park from the Roberto Bustamante Wastewater Treatment Plant ended on 2 February. The wetland cells are now dry, as is over 50% the old river channel.
Our pair of White-tailed Kites, first seen 25 May 2024, has now been present for over 9 months..
Burrowing Owl activity has been slow, but owls have been seen in recent weeks at 4 different burrow sites. A Long-eared Owl near the old river channel on 28 Feb was a nice surprise.
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.
