Song or call & method of delivery: | None.. Dang It! If only. |
Behavior: | Perched on a fence intently watching the larger insects flying by. When it spotted one it liked it would fly out and grab it. I saw it eat several large dragonflies. It coughed up a couple of pellets while I was watching it. It eventually moved up to the top of some tall cottonwoods and was flycatching from there. |
Habitat: | On a fence between a dirt road and a small canal with marsh vegetation growing in it. Open fields and Airport Runway to the north, Open Utah Lake marshes on the south. It spent most of the time on the fence in the wide open with no high vegetation around. Just before other birders started to show up it moved up into some cottonwood trees down at the southwest corner of the south extension. While in the cottonwoods it perched near the tops of the trees on the more sparsely leaved branches. |
Similar
species and
how were they eliminated: |
Western Kingbird - This bird's bill was much larger than a Western. The chest
was yellow and the belly was brighter yellow. The tail was brown, not black, and
didn't have white outer web of outer tail feathers. Wing feathers had pale
edging. Couch's Kingbird - Having little experience with Tropical and Couch's Kingbirds I am hoping someone with more experience will take a look at the photos and help me out. My reasons for leaning towards Tropical is what looks to me to be a very long bill. Whenever I got a straight profile view the bill looked very long. I know bill size on these two species can overlap but based on the photos and field guides I've looked at this bill seems on the long side for Tropical and maybe out of the range of Couch's. The green back looks duller than many of the photos I've seen of Couch's Kingbirds. |
Previous
experience with this & similar species: |
I have never seen a Tropical Kingbird before. I have seen a few Couch's Kingbirds in Texas but that was 12 years ago and I identified them by voice. |
References consulted: | The Sibley Guide to Birds App in field. Photos on the internet and other field guides when I got home. |

Additional_Comments: | These photos are stills taken from several short videos. If there is some angle not in the photos that you feel may be helpful I may be able find it somewhere in the videos. I shot videos hoping that if the bird vocalized I would catch it on the recording but it never made a sound. I wish now I would have played some calls to try to get it to respond. |
