  1. The bill looks like a cross between a redhead or Scaup and a cinnamon teal due to color and the lumpy shape . The plumage and shape could also be said to look like a hybrid of those ducks. Of course, the hybridization of those two ducks must be extremely rare. I don't think it's a domestic mounted. I guess we will need to wait for Tony Luekering to tell us or at least give the most educated guess.
  2. I'm familiar with the Orchard Oriole because I lived in the Midsouth for years. It definitely looks like an Orchard Oriole but isn't it strictly an Eastern bird
  3. Location: Ferndale, California approximately 100 miles south of the Oregon border in the Eel River Valley 4 miles from Pacific Ocean. Habitat: edge of small town long-established residential backing up to creek and agricultural pasture. This bird has been constantly feeding at my hummingbird feeder for the last three weeks. I've only lived on the West Coast a couple of years and I thought this was a Bullock's Oriole female (I don't think it's an immature male because of no black throat). I was surprised to see it here this time of year. After getting this picture of it (Dec 15)I think it's a Hooded Oriole because of completely yellow belly, longtail, and bill. It appears neither would be expected in this area, especially the Hooded Oriole, this time of year. So, which oriole is it or is it something I haven't even thought of.
  4. Notice the black butt, male gadwall is the only duck with that feature and it is a dominating one when seen from the side or rear.
  5. It is definitely a black duck. The yellow bill means it's a male.
  6. The 1st.does appear to have a very large bill which would indicate cinnamon but is all of that bill or is there vegetative matter making it look big>
  7. I agree the body shape confirms its dead, but I believe it's out of area for a birb.
  8. Definitely a Greenhead on the left and sure looks like a female mallard on right to these old eyes.
  9. In the air 2 green-wing, 2 blue-wing it ought to be clear which is which. Shovlers and teal on the water.
  10. Definitely full blooded Mottled Ducks. Notice how the bills of the Texas/LA sub-species are identical to a mallard - male yellow, female orange w/ black splotches.
  11. Added: in the close-up picture of the middle bird if the eyes only appear yellowish instead of a golden yellow it's a juvenile male rather than an adult in eclipse plumage
  12. A male shoveler has yellow eyes. Eclipse plumage makes it look female.
  13. Nevermind about the speculum. I was thinking of a Black Duck not having white edges. That speculum is perfect for a Mottled
  14. Tony, I have a couple of questions for you. 1st, when you say "too much streaking on the cheek for a male" I assume you mean too much streaking for a typical pure male Mottled Duck rather than there is a question whether the duck is male or female. Am I correct that the bill color is definitive that it is a male Mallardine. 2nd, you've taught me that tail doesn't indicate Mallard, but in the second picture of the duck the rear edge of the speculum shows some white. Doesn't that indicate it must have a little bit of Mallard DNA, although the rest of the bird's indicators are within the range for pure Mottled.
  15. I would say Duck # 1 is a male mottled duck with a little bit of mallard ancestory and the duck in the third photo is a male mottled x mallard.
  16. At first I thought there was too much white on the side for it to be pure Mallard, but that probably is just overexposure. I understand the term "intersex" is used for any bird with exterior male and female characteristics. However, in mallards I believe it is invariably a female whose ovaries had been damaged by age, disease, or injury. The bill color never changes and the plumage, due to lack of estrogen, exhibits some male characteristics. It ranges from just an upturned tail and maybe a little grayish tint to this girl who is almost full greenhead. I think in some passerines it's just the opposite where a lack of testosterone causes a male to show some female plumage.. If I'm mistaken feel free to correct me.
  17. I don't know much about domestic Mallards other than they're fat and weird colored, but the bill on #1 duck is a classic female orange and black. Could this be a Mallard mutt female with severely damaged ovaries or do some domestic breeds have males with this bill color.
  18. I agree. The photo is blurry with weird lighting, but the first photo shows the speculum and I don't believe it could be any other duck.
  19. The last pic makes me comfortable in saying it's male
  20. Not sure but I think its a male. The bill is more yellow than green and you would expect male Mallards to be hanging out together this time of year.
  21. The bird in the second photo is a male Mottled Duck. Yellow bill make it a male and Buffy cheeks, short eyeline, gape spot and under tail coverts look like a purebred Mottled Duck. The other duck has a weird bill. It's hard to tell the color of the bill and the shape is hard to discern due to glare but the plumage looks like a Mottled Duck. Maybe it's the female Mottled Duck and just has a large deformed bill or the lighting is making it look so.
