Field Marks and
Size - 7 1/2" - 8" there were Killdeer close by to compare with *
this species was just slightly smaller & slightly slimmer.
Colors - Fairly nondescript, tannish brown back, wings & head.
Stomach or belly white, buffy breast.
Head- Indistinct white facial markings with faint white line over eye
Throat - white.
Legs - Pale, greenish-yellow legs
Crown - a bit darker tan than back & wings
Beak - Short, darkish & not as thick at base as Am. Golden or Black-bellied Plovers. It wasn't needle-like like a yellowlegs or a phalaropes bill.
Wings - Tannish. No visible barring, mottling or stripe. Did not cause it to fly.
[Field marks which were not seen. Why not?]
Thin, white wing-stripe
Black tail band with white border.
Bird didn't fly. We didn't want to spook it; give others a chance to observe it.
|Song or call & method of delivery:||No sound emitted|
|Behavior:||Was feeding alone in an area near edge of lake with Killdeer nearby, but no interaction was observed between them. The Mt. Plover would run quickly a couple of feet, stop, look at ground & then quickly "catch" a food item from surface of dry or slightly wet ground. It never went into the water. When we attempted to move closer it would move quickly away & then would bob its head. More accented bobbing motion than any other plover I have observed. Tail & posterior part of body did not bob at all.|
|Habitat:||Exposed mud flat with salt grass scattered & to a length of about 4-6 inches. Other shorter species of grass also. Wasn't really a mud flat, but portion of field exposed by receding waters of Ut. Lake.|
were they eliminated:
Lacked any distinct breast bands, more yellowish legs than Killdeer. Back
was not mottled as in black-bellied or Golden Plovers. Uniformly
Dave & I watched this bird for apr. 15 min. in excellent light after conditions (see below [drawing of sun behind observers]), with sun almost to our backs & low in sky (late P.M.) coloration was drab (just like the rendition in Robbins, & even though a couple of good field marks were not observed, there isn't another plover it could have been. It was too large for any peep (there were 100's of Westerns & 4-5 Baird's around with which to compare) & too small for yellowlegs. Due to lack of mottling on back & slight smudge across breast we felt confident of I.D.
this & similar species:
Plenty of experience with Killdeer & Spotted Sandpiper. Wasn't either of
Very minimal with winter-plummaged plovers such as Golden & Black-bellied.
None with Mt. Plover - "lifer"
