Recent Birds at Rio Bosque

Water deliveries to Rio Bosque from the adjacent Roberto Bustamante Wastewater Treatment Plant resumed 4 June.  The long dry sections of the old river channel within the park are starting to flood again, but the water is advancing very slowly. Only small areas in the wetland cells are receiving water. 

The pair of Harris's Hawks that nested near the park recently fledged 2 young. 

Burrowing Owls are being seen at multiple locations.  Look for them around the artificial burrow structures located on earthen mounds scattered throughout the park.  Young birds are starting to appear. 

The Olive-sided Flycatcher found near the Wetland Trailhead was last seen 16 June.  

Summer-resident breeding birds have, for the most part, arrived.  First-of-season dates:  Black-chinned Hummingbird, 31 Mar; Western Kingbird, 31 Mar; Swainson's Hawk, 3 Apr; Ash-throated Flycatcher, 11 Apr; Green Heron, 18 Apr; Bell's Vireo, 23 Apr; Yellow-breasted Chat, 27 Apr; Lesser Nighthawk, 28 Apr; Painted Bunting, 1 May; Summer Tanager, 8 May; Blue Grosbeak, 15 May.  We are still waiting for the first Yellow-billed Cuckoo detection.
