観察結果の詳細
Continuing crisp first year male found by Jon Feenstra on 9-11-23. Located on private property, no public access. (Hummingbird last seen on 9-14-23; no longer present). My ebird field notes on 9-12-23: After not being seen this morning, the Ruby-throated Hummingbird was spotted by Curtis around 11:05am. Hummingbird with bright green back extending along hindneck to crown (beautiful iridescent green crown best seen in light; back more obviously lush green even in shade), blackish folded wings with pointed (not clubbed) final primary tip seen with scope (and in photos), dark lore and eyemask, white spot behind eye, contrasting whitish underparts with dusky buff-olive sides, white front collar and a strip of diffuse vertical white down chest. Shorter bill than many Black-chinneds present nearby. Whitish throat with fine speckling arranged in vertical/diagonal formation. One or two rosy red gorget feathers on lower left chin. Whitest area on head immediately below and center-front of eyemask before throat spotting begins. Noticeable white on rounded tail tips spiked with black above. Low-contrast dusky spots on whitish undertail coverts. Dark legs and feet. Overall, this hummingbird appeared brighter with more contrast compared to other hummingbirds present. Behavior: The Ruby-throated Hummingbird was not around early when an adult male Black-chinned was present and many Black-chinned Hummingbirds (mostly young males) chased other birds. Ruby-throated arrived after the adult Black-chinned departed for a bit and soon became “king” of the feeders, chasing other hummers and returning to a few favorite perches in a nearby mesquite tree and the wire holding the feeders. Later in the morning, the Ruby-throated held bill open several times probably due to the heat and frequently fanned tail feathers into two lobed sections (silhouette shape triangular when facing us with fanned tail). Eventually the adult male Black-chinned returned and they mostly left each other alone. We observed the hummingbird with our binoculars, scopes and cameras for over an hour (11:05am to past noon), then off and on later. Last photo taken around 2:40pm. Details and photos submitted to CBRC for review.
