Field Marks and Identifying Characteristics: |
A black bird with white spotting, vertical white shoulder bars, and red head,
into breast which appeared buff (did not get good looks at belly as it clung to
tree). It had a slight mustache stripe which was not as substantial as
Williamson's, Red-naped, or Yellow-bellied Sapsuckers. There was no other white
other than a white dot near the eye on the head/neck as in other sapsuckers. The
spotting on the back was random and not extensive as in the Red-naped winter,
nor was it extensively barred like the Yellow-bellied (or Williamson's female)
or all black like the Williamson's. There was no brown, but the head and neck
feathers were a rich, deep red, bordering on maroon. It looked very much like
the 'daggetti' subcategory of the Red-breasted as seen in the following
article
on hybridization: In fact, in looking at that article, although this bird appeared well outside its range, it did not appear to have any characteristics of hybridization as described in the article. From the article: "Race daggetti: White at the base of the bill extends as fairly broad moustachial stripe, occasionally across neck to back; often shows white behind eye, occasionally extending as a short eye-stripe; head and breast paler than ruber, some- times tinged with pale purple; in autumn, red coloration appears duller and darker, but becoming brighter through winter and spring as browner feather-tips wear away. Some black feather-bases often show through on crown and breast, especially when very worn in late summer." This appears to be a description of the bird I saw. I will send photos (5 large files in separate emails to be sure they all arrive). (see photos) |
Song or call & method of delivery: | none |
Behavior: | clinging to tree about 4-5 feet off ground. Sharing tree with Hairy Woodpecker. I zoomed out a lot of the tree, but it appeared to have old rows of sapsucker holes |
Habitat: | riverside forest |
Similar
species and
how were they eliminated: |
I scoured the guides (Sibley, Merlin, Peterson, BirdsEye), I posted on the ABA What's This Bird FB page (got no consensus), and Googled several sites. After careful consideration of all of the above, and as mentioned above, I rule out Williamson's due to its lack of red on the head and spotting on the back; I rule out Red-naped due to it's more extensive white striping on the face and neck, including the eye stripe, which is only a dot in the bird I saw. Also ruling out Red-naped is the lack of extensive spotting/white markings on the back. The bird I saw had less spotting than any of the other sapsuckers. I rule out Yellow-bellied again on the basis of the extensive white striping on the head, face, and neck of the Yellow-bellied and extensive barring on the back. This bird does not appear to be a hybrid as its characteristics fit a worn, dark red feathered 'daggetti' form. |
Previous
experience with this & similar species: |
I live in Maryland, and am a member of the Howard County Bird Club, one of the most active in the country. I go on regular walks with the folks who have been birding for decades. Although my experience is not as extensive, I have been a life-long birder, having started with my father when I was 3 or 4. I am quite familiar with the sapsucker here in the east (we have one!), but also with the myriad of woodpeckers found here. |
