I spent about 40 minutes or so this afternoon (feb. 10) checking the fields in Alviso from various vantage points (Disk Drive, Los Esteros, the church parking lot). There were groups of Canada's, but I didn't find the Cackling Geese. But a little later (similar to Bill's recent experience), at 3:40 PM, the flock of 14 CACKLING GEESE had appeared close to the road at the end of Disk Drive (where it makes a 90-degree left turn to Grand). I am inclined to call these Aleutian: most (all I could see well) had a prominent white collar in front, and I didn't think they were particularly dark below. I found it hard to tell much from bill shape/size. The birds did look fairly small compared to adjacent Canada's. (Has it occurred to anyone that maybe the local Canada's are getting bigger? No? But perhaps our perspective is influenced by the fact that the birds were mostly standing in grass, so a smaller fraction of a Cackling was visible.)
