> Lots of people have offered various evidence that spring's early  
> this year, so I thought I'd mention that the first egg at Marty  
> Leonard's Tree Swallow boxes near Gaspereau and Wolfville Ridge was  
> laid c. 6 May this year.
>
> That's four days earlier than last year's first egg date, and a  
> full 11 days earlier than the median (middle) lay date since 1994  
> (when Sherman Boates and co monitored the sites). It's the earliest  
> lay date since those records began.
>
> Plus, the earliest lay date is often a bit of an outlier, happening  
> a few days before most of the birds really get going. But this year  
> it seems to be the real deal, with more and more nests having eggs  
> each day since the 6th.

> Cheers,
> Andy Horn (though the observers were Hendrik Reers and Sarah McGuire)
