Specific Locality: |
Cameron Prairie NWR Wildlife |
Date(s) when observed: |
March 20, 2010 (also, paired M and F seen by Conover, Myers,
Patton on 3/28)(pair—presumed same—seen by Conover and Myers on 4/3) |
Time(s) of day when observed: |
Late
morning on 3/28; afternoon on 4/3 |
Reporting observer and address: |
Paul Conover |
Other observers accompanying
reporter who also identified the bird(s): |
Charlie Lyon (3/20) Mac Myers, Dave Patton (3/28) Mac Myers (4/3) |
Other observers who
independently identified the bird(s) |
I
think a few others saw the bird. Charlie mentioned that he and Kraig Ellzey had seen a
Cinnamon Teal (I think) in the same spot a week or two before. Tom Finnie and
Melvin Weber reported seeing at least some of the birds as well. |
Light conditions
(position of bird in relation to shade and to direction and amount of light): |
Birds were to the NE; sun was overhead and
right at about the equator as it was the spring equinox. Clouds passed over
the sun intermittently but overall the light was bright. |
Optical equipment: |
Binoculars, Nikon Fieldscope III ED 20-60
zoom, Sony camcorder with 60x optical zoom in conjunction with scope. |
Distance to bird(s): |
about 100-150 yards |
Duration of observation: |
about 30 minutes |
Habitat: |
Shallow freshwater marsh. The birds were in
last years’ dead emergent grass. |
Behavior of bird: |
Birds
swam and tipped up to feed on the bottom frequently among the grass. |
Description: |
Drakes
were straightforward male Cinnamon Teal. I looked for signs of hybridization
and found none. Even, bright reddish
color on head, neck, and underparts. No spotting of any kind noted on red of
this area, nor were there any extra markings on the red of the face. Darker,
almost blackish dorsal stripe the width of the crown running from base of
bill through hindneck. Back seemed mottled, with paler feathers with darker
internal markings (but overall a slight though noticeable contrast with red
of body)(actually, in subsequent viewings, the straw and dark mantle seemed
to either contrast noticeably or slightly depending on how much of the mantle
was visible. At times only a sliver of mantle was visible from the side; at
others, a wide slab of mantle could be seen. The more visible the mantle, the
more contrast). Wingtips were blackish. Tail looked blackish as well—I know
there should be pale there as well, but the birds were swimming and sleek and
that was not visible. Long, pale scapulars showed up as thin stripes running
longitudinally. Bill black, long, and
spatulate. Eye red. The
female was obviously a Cinnamon Teal, but I spent much more time studying her
to look for markings to provide convincing proof of her identity. Female was
identical in morphology to males. Overall, female was a warm, fairly even
brown. Head and neck paler than rest of body but not strongly so. Sides of face were very plain brown, with
no obvious streaking. Pale area at base of bill extremely limited in
comparison to female Blue-winged Teal. Like male, female had a darker dorsal
stripe the width of the crown running from bill base through crown to
hindneck; this stripe appeared dark brown. Bill black, long, and spatulate as
in male, with fairly straight culmen. With neck straight up as bird swam,
bill stuck out at a downward angle. Eyes dark. Legs bright yellow,
contrasting strongly with body. Body
feathering below on underparts and flanks with little contrast between
internal markings and fringes. As the duck tipped downward, the warm brown of
her undertail and vent were obvious; this color was largely concolorous with
remainder of bird’s underparts, and I think this might provide a point of
separation between hens of BWTE and CITE. Wings slightly darker than rest of
bird. Female
was clearly paired with one of the drakes.
Both drakes were aggressive towards BWTE that approached too closely. |

Similar species: |
BWTE and
BWTE X CITE the only real contenders. Males;
BWTE X CITE: I looked for signs of hybridization but no markings that were
inconsistent with pure CITE were seen. The previous weekend, I had been given
a good demonstration of skins of this hybrid pair and noted the areas where
mixed markings occurred. None of these areas were affected on these birds. Female;
BWTE: Morphology, especially of bill, consistent with CITE and identical to
associated males. Bland face pattern, overall color consistent with female
CITE and strongly different from female BWTE.
I also viewed
the vent and undertail color of this bird to nearby BWTE females on 4/3 to
test the idea that CITE females have less marked, browner color in this area.
BWTE seemed to be paler, whitish, speckled. The CITE, as I recall from 4/20,
was warmer brown and less speckled if it all. Regardless of exact markings,
the areas seemed to differ. |
