In 30 years, the bay area has built up a large population of non-migratory birds, mostly geese. Why did they stop migrating? Do some of the goslings decide to follow the rest of the flock and migrate, or do they all become a charter member of the permanent flocks? Is this happening anywhere else..

In the bay area, there may well have been geese resident all year all along, just in very small numbers. You could be seeing an increase in numbers. Most cap cod residents will claim that the geese started to stay behind ther in the 60s or 70s but I’m pretty sure they were there since before WW2, just in small numbers.

I look forward to reading your posts! I have only been ‘interested’ in birds for about a year now, but they are truly fascinating – especially in terms of migrations. Two of the topics that most intrigue me are the control of the timing of migration (I work on seasonality in insects currently) and the evolution of migratory behavior.

The amazing thing about studying seasonal timing in birds is the true participation of citizen scientists!

Again, can’t wait to see the set of posts you have and maybe this is the inspiration I needed to get back into blogging!
