Recent Birds at Rio Bosque
Water deliveries to the park from the adjacent Roberto Bustamante Wastewater Treatment Plant resumed 4 May. The park's wetland cells are again receiving water, albeit less than they do in winter.
Summer resident birds are largely gone. Good numbers of passage migrants continue to move through. Lesser Nighthawks have been present for several weeks now; a Common Nighthawk joined them 27 Aug. Soras are calling at multiple locations.
White-tailed Kites continue to be seen intermittently, as do the park's resident Harris's Hawks.
Burrowing Owls are still being seen regularly, with immature birds now also appearing at burrow entrances. Check the artificial burrow structures located on earthen mounds scattered throughout the park.
A Great Crested Flycatcher on 5 Sep represented the 255th bird species detected at the park.
No Northern Cardinals have been detected since 31 Aug.
