[Bluebird-babble] Hi

[CBPKevin@aol.com]

Hello Pat,
    Welcome to the bluebird babble listserv!  The timeframe of nest-building 
you're seeing at your nestbox sounds about normal, they often take a week or 
more to build a nest.  The nestcup is the last bit of construction, so it 
sounds like they're almost done.
     I tried to look at the Cornell reports for date-of-first-egg but 
couldn't get into it today.  You might want to try it.  Go to 
www.birds.cornell.edu/birdhouse, click on the NEWS AND RESULTS block, then click on the QUERY TBN 
DATA line, then select your query parameters.
    I can tell you that last year the first mountain bluebird egg recorded on 
the trail I help monitor appeared on April 21, another was on April 24.  
Those were early nests, most of our MOBL nests didn't put down the first egg till 
around the 4th - 8th of May, the latest was  May 18!  Our nestbox trail is 
south of Larkspur in Douglas County, open grassland, elevation ~ 7,000 feet.
   Hope this helps!
