MEGA. First report for NM. At approximately 10:30am (Mountain Time), while sifting through Western Tanagers along the mulberry row at the entrance to Washington Ranch, I laid glass over a slender oriole with an all black head, bib, and back. The bill was decurved like a Hooded Oriole, and mostly dark with a contrasting silvery base to the lower mandible. The distal half of the flight feathers, and all of the tail, were obscured behind dense leaves but I could clearly see that the bird’s wing was all dark, except for a crescent of yellowish-orange plumage in lesser coverts (like the yellow upper wingbar of a male Western Tanager). Any other expected oriole at this location should show some amount of white in the wing, either as a lower wingbar or as a sizeable wing patch. What I could see of the underparts was that the belly was bright yellowish-orange, about the color of an apricot. Then, just as soon as I saw it, it was gone, dipping out of the back of the tree exposing a long black tail. I did not make observations of lower underparts, or undertail coverts at this time. It’s important to note that unfortunately this observation happened over mere seconds, and I was in a bit of disbelief about what I was seeing. It was brief enough that I was unable to get any photos. I have encountered Black-vented Orioles multiple times in Mexico, so I knew what I was seeing. Thankfully it’s an easy quick ID as nothing else much looks like it in the USA. Shortly thereafter Jacob walked up (very little cell reception here) and I alerted him to what I’d seen. We spent the next 30 mins or so hanging around the initial observation location trying to a again before alerting the NM/TX community. About 11:00am it called from a nearby cottonwood, giving a distinctive short nasally “myeah” call, which I’ve heard many a time in Mexico. Jacob managed to record two call notes spaced a few seconds apart with his iPhone. We will upload later and update text with time stamps for when the bird vocalizes, I’m afraid it’s fairly soft in the recording but certainly audible. We walked to the tree where the bird had vocalized and it flushed (along with about 30 other birds) deep into another large mulberry. When it flushed it flew over Jacob’s head but he wasn’t able to get it in the nocs. Shortly thereafter another bunch of birds flushed across the road. As I scanned through the tree they landed it I located it again and saw it for another two seconds before it flew. and was able to see it from a side profile. This time I was able to quickly note everything I’d seen before but in the open and was able to appreciate its very long black tail and black undertail coverts. It flushed and we never saw it again. We did spend all of the rest of the day searching to no avail. Winds were gusting up to 30mph, for much of the day and there were hundreds of birds to sift through, all of which were constantly flushing all over the place due to the workers mowing the lawn, driving their trucks around, and hacking away with axes at the new growth on the tree trunks. We plan to be there in the morning at first light in hopes of getting photos. ***ADDITIONAL NOTES FROM JACOB Well we heard the oriole in the large cottonwood on the north side of the more eastern pond and not soon after I got the recording we where to trying to locate the oriole in the tree. As this was happening the oriole flew out of the tree with another bird (was not paying attention as to what probably a WETA) and over my head. It was noticeable larger then the bird flying next to it and a lot more slender. I was able to see the black head extending down to the chest with the black not stopping on the sides of the bird telll about where the wing started and then dipping down into the breast in a semi-oval shape. The body was orangish-yellow but lighting made it really hard to discern the exact shade. I only really was able to see there was some yellow also on the upper half on the underside of the wing the rest being dark. The tail was very slender and all black from my view it seemed like the black went into the birds body which I believe is the undertail covers or vent area which I believe is along with the calls is diagnostic for BVOR. I saw this bird only in flight.
