during observation]______________________________________________________ |
4. Date(s) when observed: 14 May 2011 |
|
5. Time(s) of day when observed: 2:40-2:55 p.m |
|
6. Reporting observer and address: Robert Purrington, 4700
Bissonet Dr., Metairie, LA 70003 |
|
7. Other observers accompanying reporter who also identified
the bird(s): |
Conover,
Myers, Wallace, Sorrells, Patton |
8. Other observers who independently identified the
bird(s): same as above |
|
9. Light conditions (position of bird in relation to shade
and to direction and amount of light): clear sky, seen from all directions
relative to sun |
|
10. Optical equipment (type, power, condition): 10x42
binoculars |
|
11. Distance to bird(s): never less than 200 f t |
|
12. Duration of observation: about 15 minutes, but not
visible entire time. Perhaps 2 minutes
of continuous observation |
|
13. Habitat: scrubby chenier woods, mix of hackberry and
acacia/mesquite |
|
14. Behavior of bird / circumstances of observation
(flying, feeding, resting; include and stress habits
used in identification; relate events surrounding observation): Conover found
the bird and called us on Myers’ cell phone, saying he had an “odd
woodpecker.” As we ran toward Conover
the discussion centered around the likelihood of Laddder-backed.
Then we heard the bird call and it flew directly over us (myself,
Myers, and Patton, I think) and landed in a tree-top about 75 yards
away. One look and everyone one could
see the head/face pattern and ladder back, and
simultaneously identified it as Ladder-backed. Conover came over shouting “Ladder-backed”
as well. After 20-30 seconds, the bird
flew to the north. Wallace and I went
about 100 yds north to the next E-W clearing, and I played a Ladder-backed call, whereupon
Wallace heard the bird “reply.” We
went after it and picked it up in a tree top, from which it almost immediate
flew, back toward the south again.
After 2-3 minutes we picked it up again, in a tree-top, then flushed
it 2-3 more times until it was near the parking area at the lighthouse. Finally it took, flew over the canal, past
the lighthouse, apparently landing in the woods just being the lighthouse,
on the edge of the river. We scanned
those trees for about 30 minutes, constantly playing tapes, but to no
avail. It is not known whether it crossed
the river, which was only ½ mile away. |

15. Description (include only what was actually seen, not
what "should" have been seen; include if possible: total
length/relative size compared to other familiar species, body bulk, shape,
proportions, bill, eye, leg, and plumage
characteristics. Stress features that separate it from similar species): the
bird was a smallish woodpecker with bounding flight, had a black-and white
“ladder-back”, an extensive red cap, and a face pattern consisting primarily
of two parallel black stripes, one through the eye, the other extending
toward the bill. The bird called
frequently and Wallace recorded calls with his video. |
|
16. Voice: sharp, somewhat Hairy-like. Recorded by Wallace on video tape. |
|
17. Similar species (include how they were eliminated by
your observation): very superficially could be said to resemble the larger
Red-bellied, except the red was redder and did not go down the nape at all. In fact, none of the Melanerpes
woodpeckers have similar face patterns, and the same goes for other species
with similarly patterned backs, belonging to Colaptes,
Dendrocopus, Dendropicos,
etc. Call, which resembled a Hairy Woodpecker was totally different as was the face
pattern. The only credible
possibility among North American woodpeckers, though far out of range, would
be Nuttall’s.
But on this bird almost the entire crown was red and the calls were
quite different from those of Nuttall’s I listened
to and matched Ladder-backed exactly (using the calls on the e-book version
of Sibley). The bird responded to
Ladder-backed calls. No hint of
hybridization, e.g., with Hairy, which is known to occur. |
18. Photographs or tape recordings obtained? (by whom? attached?): Photographs by Conover, Patton, and
myself, at least. Video by Wallace,
with audio. My photos not
attached—Conover’s are very much better, plus Patton’s flight shot. |
|
19. Previous experience with this species: Numerous times
in west-central to west Texas. |
|
20. Identification aids: (list books, illustrations, other
birders, etc. used in identification): |
|
a. at time of observation: none |
|
b. after observation: Sibley,
primarily, to check details of face pattern and to compare with Nuttall’s. |
|
