The first order part of the propagation (day vs night) can be roughly estimated. Do you get two eight hour long “windows” of data each day or is it more? If your local standard goes into holdover for 8 hours, is that better or worse than tracking a couple cycles (at 60 KHz) of swing?

I estimate that there must have been at least a thousand birds on that one tree.   While I was watching, a car went by, the birds flew up briefly but all returned to the tree.  A bicyclist went by, and many of them left and some returned. 

Please also send any reports you may have to ctwaterbirds@gmail.com, along with an estimate of how much time you were out looking for them. Thanks!

I can only estimate their numbers to be 300+ (?). 3 Red-throated Loons were fishing close off Russian Beach and Long Beach. There was a bounty of Waterfowl mixed in with the Gulls and Brant so I started looking through the ducks. In one of the small flocks of feeding Scaup were a high percentage of Lesser Scaup. I never checked the others.

Perhaps volunteers could contribute in-kind services such as preliminary engineering work and project cost estimates as matches for a grant submission. You should expect to be contacted by Rick Potvin to discuss possible funding and implementation strategies in an effort to move this concept toward a reality as a community based asset.

Given the highly contagious nature of this virus, and the fact that we know so little about its true prevalence in the human population (some estimates suggest that less than 10% of cases have been identified), we feel it is not prudent at this time to take risks. Consequently, we have decided to add another breeding season of data collection during 2021.

The latter I'm guessing are those most likely to be unsheltered and for whom changes in affordability and increased employment opportunity will not work, but who need either mental health services or addiction services without any current statistical estimate for a high percentage of long term success.
