2007 Wrap Up



Here is the final total count of banded hawks for the years 2001-2007. We ended this season with 280, which puts 2007 as the fourth highest season overall and the third highest as of October 6, which was our last day this year.


This graph shows the average number of hawks banded per day for the years 2001-2007. This season was the third highest at 6.8 per day.


This graph shows the total number of each species we banded and compares that to the average number banded over the 2001-2006 seasons. This year we were higher than average with Cooper's Hawks and American Kestrels, and lower than average on almost everything else. We banded 10 different species this year. Over the years we have banded 11 different species, but we have yet to band all 11 in one season.

And that gives us a goal for next year!

2 More Banded - Sunday, September 23, 2007


What a joy to be so happy with small things.

Jim and Kaitlyn got us through another day with at least something banded. They saw 35, which is more than we have been seeing the last few days, but most of the raptors today were showing little interest. They did have some fun watching another Golden Eagle coming in close and an adult Peregrine Falcon making many passes.

Raptors banded:

1 AHY female SSHA
1 SY female SSHA

Here is a graph showing the average # caught per day during 2001-2006. As you can see, we traditionally have a slow period mid September. Our busiest week historically is this coming week. Any bets on whether we will top our biggest day so far of 26?



Here we see the species breakdown for the years 2001-2006 compared to what we have banded so far in 2007. It appears to be the "Year of the Kestrel". Our Cooper's Hawk numbers are above average also, while some of the other species are below average. It is still too early to speculate, but on those slow days in the blind, what else is there to do? Suffice it to say, at this point, anything could still happen.

Comparison graph for all years

Here is a graph comparing the total banded for all the years since we started the project in 2001. We have just slipped behind 2006, which was our best year to date. Not to worry though, we have a long stretch of good weather coming up.

Clicking on the graph will give you a larger view.



Here is a link to our published report of the Entiat Ridge project from 2001-2005:
