  1. I think it is a hybrid. I don't like using size because we only have Canadas for size comparison. Also, unsure exactly how close the birds are together. There is not a good profile picture showing bill angle. It looks like the bill angle in the second picture is more like Ross's than in the first picture. So, turning to the grin patch, it looks like the first picture shows a grin patch that is too prevalent to be a pure Ross's, and in the second picture the grin patch is not significant  enough to be a pure Snow. I conclude it is probably a hybrid, but not sure these pictures are definitive.

  2. I spoke too quickly in saying that the goose had no greater white fronted genes. I didn't think that hybridization could cause an eye ring because the GWGO (?) Doesn't have an eye ring or any white around the eye just the forehead. I looked up some hybrid pictures and did see a goose on E Bird listed as a hybrid with a white eye ring. I don't know what the hybridization is. Maybe the size is because of hybrid vigor. Does hybrid vigor occurring waterfowl. Mixed with a graylag is still a strong probability.

    I think the figures on the left are people with umbrellas.  One umbrella is red.

    You are correct. That definitely impacts the meaning of the painting as a whole. This reinforces my belief of water birds, as behavior is important in this painting more than color or exact shape. 
    Of course, others interpretations may vary.

    The painting is by Arthur Lawrence Jones (1910 – 1996), who painted under the name Lawrence Arthur. This was an interesting diversion, thanks for posting Jerry. However please do not post any paintings of birds by Picasso for identification.

  4. I believe they are water birds but not waterfowl. The line is bending and a line of geese would be straight.  I eliminated crows because I've seen many many crows in my life but I've never seen any flying in any formation that resembles a straight line, ravens don't flock at all but are solitary or paired. They seem to  represent gulls, cormorants or little blue herons to me. I'm also influenced by what I perceive as a yellow sunset sky and water the birds are flying towards.

    Also, in the lower left of the painting that appears to be a flock of redwinged blackbirds.

    The second picture – a classic view of geese flying directly away from you. Since there is no depth perception you don't know if those six geese are flying in a line or in the V. But there most definitely in formation. Notice how every goose's wings are in the same position i.e. essentially horizontal to the ground and they are equidistant apart. They probably only moved about 100 yards since the first picture and is highly improbable they would have changed positions and be back in line in that short of distance.  So the white goose has one Canada about 3 yards ahead of him to the left and one Canada about 3 yards behind him and to the right in each picture

    first picture – there is what is obviously the lead goose, the two uppermost geese form the "left" side of the V looking from the rear as in the second photograph. The white goose is the first goose on the right side followed by two Canadas (third from the right just like in the second photograph). When you look at the picture looking at each "line" including the lead goose, you see the left line is straight and right line is fairly straight but a little off because the white goose is not creating the same wind current. So in this picture the lead goose will be slightly closer to the camera than the white goose and the two Canadas in the lower right of the photograph will be slightly further away.

    Edit: the first picture looks weird because the white goose is so small. Take him out and you can see the V. But he must be in formation based on the second picture.

  6. Charlie, when you look at both of those pictures together, you can tell those geese are flying in perfect V formation. 
    So, I don't think the large size difference is an illusion. I don't think the photo shows the goose well enough to rely on anything other than size. Even the snow goose is going to look small flying with Canadas, but that goose looks really small. I surely wouldn't say conclusively it is a Ross's but with the size difference so great, I would give it a strong probability.
