In other words Crotty wasted a lot of his time, and any body's who read the
whole article. A package of garden seeds might have set the dude on a more
productive path with climatic zones map.

Hi Tim & All,
I just noticed something in the Crotty paper that might explain the
problem:
"All eBird checklists submitted in a five-county region surrounding each
historical observation location were included in the analysis to establish
a sufficient sample size to assess temporal occupancy patterns."
A five-county region around Coos would be, I suppose, Coos, Curry,
Josephine, Douglas ... and then take your pick for the last one. Jackson,
Lane, or Del Norte?
Including Douglas County, Lane County, and/or a couple of inland counties
could make a big difference in the outcome.

... I have attached an excel spreadsheet with the first arrival date
info I have for Rufous Hummers in Coos. Based on these data ...
the average arrival date is 10
February for the period 2006-2015 that the Crotty article analyzed. The
chart in the Crotty article shows the average arrival date for the period
of 2006-2015 in Coos Bay as day 70.9 which equals 12 March. This is a
month different from the observation data I have!
