Recent Birds at Rio Bosque
Water deliveries to Rio Bosque from the adjacent Roberto Bustamante Wastewater Treatment Plant ended at midnight on 30 Sep. They likely will not resume until approximately 1 Nov. The wetland cells and much of the old river channel will be dry during October.
The pair of Harris's Hawks that nested near the park this year fledged 2 young. The adults and young continue to be seen sporadically.
Burrowing Owls are still being seen at multiple locations, but less frequently now. Look for them around the artificial burrow structures located on earthen mounds scattered throughout the park. Early and late in the day are the best times to see them.
The first Eastern Phoebe of the fall was along the old river channel on 3 Oct.
