Birds included in this weekly summary are those that are considered casual or of less than annual occurrence in San Bernardino, Riverside, or Imperial Counties, or in some cases regionally within these areas. If you do find or see something of interest, whether it be a geographical or seasonal rarity, evidence of local range expansion, or a novel breeding record, I'd recommend sharing that information with the CBRC, North American Birds subregional editors, or regional listservs as appropriate. Information for contacting these entities is available below.
Please submit your documentation of all California Bird Records Committee review species (denoted by asterisks) to CBRC Secretary Tom Benson at <secretary...> or via the CBRC website: https://www.californiabirds.org/report_sighting.html
CBRC review species and birds of local or seasonal rarity should be reported to the North American Birds (https://www.aba.org/north-american-birds/) county coordinators. They are:
