Recent Birds at Rio Bosque
Water deliveries to Rio Bosque from the adjacent Roberto Bustamante Wastewater Treatment Plant resumed 27 Oct. Both wetland cells are now fully flooded and hosting good numbers of waterbirds. The old river channel continues to have dry stretches, but ~80% has water.
A Western Screech-Owl continues to emerge from a nest box in Cell 1 ~15 minutes after sunset. 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.
