This is a fairly predictable phenomenon--where inland sites have higher species diversity than coastal ones. On the Coquille Valley CBC , the Norway sector always has the highest species count--92 this year with a team of two and an area about a mile
wide and 2 1/2 miles long. Coastal sectors of the CV circle have some seabirds, but rather few choices of passerines. Reedsport is especially disadvantaged relative to other coastal counts as it has very little unforested bottomland or other features that keep inland passerines happy. The record high species counts at various coastal CBCs can't be achieved without things like Scrub Jay(a regular at Norway), Purple Finch, American Goldfinch,often species that inland counters tick off w/o a thought.
Ultimately it is the absences that make the strongest impression on me while participating in a coastal CBC. All day in downtown Langlois and Port Orford this year without a single Rock Dove. It's so seldom on the PO CBC that it doesn't make the
regular list. lpn

> Yes thanks again for all the work. I enjoy seeing those summery tables. We must have been missing someone at the countdown to have gone from 110 to 116. I suspect it was the north umpqua group as I do not remember those goldeneyes at the countdown. It was nice to see that those were found again. I remember Ron finding those pretty consistently for a number of years, but it seems like they have been hard to find the last few years. If the countdown number holds for the Reedsport countdown the 116 would mean the inland Douglas county count beat the 114 Coastal Douglas county count. This is a big surprise to me. I would credit it to the difference in the quantity of counters. I think there were in the mid 30ís for Roseburg participants and less than 15 for Reedsport.

>> As much fun as it is recording birds in our own parts of the Count Circle, your organization (Mark), tally (Jeannie) and narrative on Umpqua Birds (Matt) tie it all together to enjoy and compare with other years. Thanks to each of you for making the Christmas Bird Count for Roseburg-Sutherlin such a great time. Mikeal

>>> P.S. One of the most interesting things to me is to look at the tables I have been producing several years now, which sort the bird numbers not only by taxonomy, but by total numbers of each species and by the number of team areas recording the species. For example, can you predict which species were found in all 14 team areas? It's also interesting to see which species were found in only one team area (e.g. easily missed). Look for these tables in the blog and cbc websites linked above. mgh
