["Ankeny,Ryan Douglas" <adryan01@xxxxxxxxxxxxxx>]

Hello, my name is Ryan Ankeny and I am working the MAPS station in Ft. Knox 
this summer.  I thought I would report the results from our first two banding 
periods and update as the summer continues.  For the first two banding periods 
(from 5-17 to 6-5) the birds we have captured or banded are:

Total birds captured in the first two periods was 152.  Numbers are down from 
2006.  Some sites had as many as 30+ birds last year and this year we are 
catching around 12-15 at these sites, sometimes even less.  I wonder how much 
this has to do with the freeze earlier in the spring. 

Our goal is to sex and age each bird that we band by examining molt limits that 
occur in the flight feathers as well as in the secondary and primary coverts.  
We determine male or female by looking for differences in plumage or by looking 
for brood patches in females and enlarged cloacas in males.  Two tail feathers 
are pulled on as many birds as possible.  The feathers are sent to UCLA where 
they use stable isotopes to determine where the bird winters in the tropics.  
Also when time allows each bird is swabbed in the cloaca to determine the 
presence of avian flu.

Anyone with questions about the MAPS program or anything else feel free to 
email me.  The website for IBP (Institute for Bird Populations) is 
www.birdpop.org for those interested.  I'll update our results after the next 
banding period.   Thanks and happy birding.year and this year we are catching 
around 12-15 at these sites, sometimes even less.  I wonder how much this has 
to do with
