warbler arrival

["Leah Campbell" <faeriemaiden@hotmail.com>]

Heard my first black-and-white warbler of the season today. Does anyone know 
where I can find a list of approximate warbler arrival dates?

Also, according to all I've read about phoebes, sexes are alike in adults. 
However, I've noticed a slight size and color difference in the mating pair 
in my yard. According to my readings, the female is the sole nest builder. 
While observing the pair through binocs today, I noticed the female (one 
with dried mud on her bill) was slightly smaller and buffier than the male. 
Could this be subtle sexual dimorphism, age difference, or mere individual 
variation?

Forever curious,
Leah
