I found myself in the east end of lovely Ottawa again this weekend at Petrie Island. Wish I'd had more time there as it was bustling with birds, including this one, which was sneakily (and stubbornly) hiding behind this blade of grass but making an awful lot of noise for such a little dude. I was very excited to finally see "one of the ones with the tail way up!" Also, it is very interesting to know that the males makes about 10 nests in their breeding territory....or something like that.
