Wings - Flecked with 10 -12 blackish specks showed rich reddish-brown tones in primaries when it flew.
Tail - Dark with black borders. Never did see any white, because it flew away so quickly & disappeared into the thick, nearby vegetation.
Bill - Darker throughout lengh & going to a lighter color near base; not yellow though.
Overall size - Blackbird size, but with shorter tail & more plump body
|Song or call & method of delivery:||None detected|
|Behavior:||This bird fed on seeds & chicken mash on a dirt road just north of the large trailer at the ranch. It would crouch low while feeding with breast close to & on the ground. When it walked it nodded its head, when it flew it was only about ten yards into some plum bushes, but it was a rapid, direct flight. It stayed in the vegetation for a long time (sometimes hours) before venturing out to feed.|
|Habitat:||Trees, Bushes & Grass. Road. Ranch buildings (sheds, house, etc. & a long trailer house)|
how were they eliminated:
Common Ground Dove (Columbina passerina) - C. passerina has scaled
appearance on head & breast, grayer plumage overall.
c. talpacoti totally lacked the scaled appearance & was more rosy pink color overall.
Also, I showed the video segment to Clayton White, B.Y.U. ornithologist, who came to conclusion it was c. talpacoti. Next, we checked specimens of c.talpacoti in the B.Y.U. ornithological collections. There were 3 specimens to compare with & the bird we had on tape matched these.
Next, we checked the description in the A.O.U. checklist & also in a textbook called Doves & Pigeons of the World to determine Common Ground-Dove juvenile characteristics & compared with Ruddy Ground-Dove,. Conclusion: C. talpacoti
|Previous experience with this & similar species:||None with this one. Have seen Common Ground in Ariz. & Inca Dove in Utah.|
|References consulted:||Doves & Pigeons of the World|

|Additional comments:||Note - This is a first sighting for the state of Utah. We considered the possibility of this being an escapee from a zoo or a pet shop. But Vince Mowbray, a Los Vegas, Nev. birder, informed off a Ruddy Ground Dove north of Las Vegas & 4 - 5 in California a couple of weeks prior to this sighting. Based on this information I feel that it is more than likely a naturally-occurring bird & not an escaped one. M. Webb|
