Song or call & method of delivery: Heard typical oriole chatter
Behavior: Initial roosting sighting then foraging on later sightings
Habitat: Honey and screwbean Mesquite/tamarisk/cottonwoods wetlands/riparian some desert willow planted/palm trees around golf course housing developments - area is bullocks/hooded oriole nesting area
Similar species and how
were they eliminated:
Initially only Hooded eliminated due to straight bill - presumed to be immature Bullocks - but yellow belly seen on following sightings and discussing with Dr. JV Remsen LSU and then Kevin Wheeler - Biologist DWR UT - made the bullocks ID not viable - Kevin and I looked at the field guide on 12/31/13 and it appeared to look like one of the exotic orioles. We noticed the orange near the face and Kevin said he would get a better look. In addition- Van Remsen and Rick Fridell DWR UT made comments on the photos pointing toward a Streaked-backed. He later sent me the photos of the streaked-back.
Previous experience with
this & similar species:
None- only Bullocks/hooded and a few scotts
