Recent Birds at Rio Bosque
Water deliveries to the park from the Roberto Bustamante Wastewater Treatment Plant ended 6 Oct and are not expected to resume until late October. The wetland cells are both dry, and sections of the old river channel are dry as well.
Since 25 May, a pair of White-tailed Kites has been present. They continue to show no evidence of nesting.
Burrowing Owl activity has been slow. Rock squirrels appear to have commandeered many of the burrow sites.
Summer residents have largely moved on. Southbound migrants continue to appear, with the mix of species changing daily.
