Birders,
As we are entering the summer 2019 reporting period for North American Birds, please be on the lookout for breeding attempts or evidence of breeding from any of the following species. I do not endorse or encourage anybody attempting to find nests, but careful unobtrusive observation should make it clear if active nests are present, e.g. birds carrying food into vegetation, sounds of begging, birds seen carrying fecal sacs, obvious young birds, etc. Copulation is worth noting as well.
All of the species listed below have limited breeding ranges in the county or are no longer known to nest in the county. If you observe and/or obtain documentation of breeding, please let me know. This is retroactive for the spring period as well as the summer period that is just starting.
Blue-winged Teal Common Gallinule (particularly in any unusual locations, for patch birders) Black Oystercatcher Spotted Sandpiper (outside of the Santa Ana River or Peters Canyon Wash) Western Gull Double-crested Cormorant Least Bittern Reddish Egret Northern Harrier Belted Kingfisher Peregrine Falcon Olive-sided Flycatcher Loggerhead Shrike Mountain Chickadee (in the coastal region) Swainson's Thrush Lawrence's Goldfinch Black-throated Gray Warbler Chipping Sparrow (outside of the mountains, Craig Regional Park, or Orchard Hills) Tricolored Blackbird Redhead Virginia Rail Warbling Vireo Wilson's Warbler Purple Finch (outside of the mountains) Western Wood-Pewee Western Kingbird Horned Lark Rock Wren Bell's Sparrow Yellow-crowned Night-Heron (curious what happened to the known nest at Doheny)
