While on work at West Island area, I noted some warblers fluttering about on West Island. YELLOW-RUMPED  and BLACKPOLL WARBLERS shared the island domain as I watched from the bench spot. On the mainland, a BLACK-THROATED BLUE WARBLER ; I noted other stuff along there , a worthwhile spot for today.
3 WOOD DUCKs with a lone NORTHERN SHOVELER  under the perched GREAT BLUE HERON was another observation from that general area.
Rain oftentimes trap birds...so bring a raincoat and seek....
