Sid, great to hear about and see pics of your crane watching! It was surely cheery news. What does someone feed cranes by the way?
Went out for a chilly but sunny afternoon (3-5 pm), probably around 0 Celsius, but blessedly little wind. Didn't see any cranes, as I had hoped to, and not too much else either. But there was a late curlew and a green sand (I think, a little distant) - the latter seemed "frozen in place", hopefully not literally but he didn't seem to move. Wonder how late he is? Hopefully he knows where to head south.
Most interesting birds were buntings in the grasses on the sandflats. There were maybe 4-6 up high near the seed heads eating, but even so were quite tricky to see with the movement of the grasses. I mostly saw some almost blindingly white breast (well, in the low angle sunlight), and white malar stripes (maybe black beneath the beak? maybe black on head?). With the few glimpses I got, there are still a lot of bunting possibilites, but I have two questions, don't know if anyone has thoughts on:
1) Are buntings other than Pallas' Reed and Common Reed likely to be up in the marsh grass like that?
Yes, mostly Pallas's and Japanese Reed, Common Reed is the species least encountered
2) Do buntings hang out in mixed groups? (I'm really not sure all the ones I saw were the same.)
Yes
Oh and one related question, do other birds (buntings?) hang out with tree sparrows? I mean if I identify one in a group as tree sparrow, can I be sure they all are? (I didn't see a tree sparrow in that bunting group, but saw some elsewhere in the marsh.)
Yes they do form mixed feeding flocks, often with Rustic, Little and Yellow-throated, especially in areas like the reservoir edge
One other mystery. I thought I saw a large brown winged bird flying away from me low over the marsh. I thought it could be a hawk or owl, but I don't think it landed in a tree (seemed to disappear behind the grasses), and didn't reappear. I don't know if that brings to mind any possibilities or if the id is wide open.
Probably a Short-eared Owl, a good area for them and the right time of year!
Little egret flock was down to 6 brave (hopefully not foolish) birds fluffed up and looking cold. A few little grebes still around. A lot of ponds were frozen over and I saw only distant views of a half dozen ducks.
PS Also meant to ask - do buntings go into non-breeding plumage before or after migration? (Or perhaps it depends on the species?)
Both, not necessarily species dependant
