Not very familiar with Nova Scotia "hotspots" for wildlife photography. I'll see if John Chardine has some info, he is located closer to the maritimes and may have ideas...
1. There will still be landbirds singing (we've had a late spring!) so you will have opportunities if you come prepared to use playback.
2. The Shubenacadie Wildlife Park has captive wolves and other mammals.
3. A boat trip out from Briar Island, past Digby, should yield whales (too early for phalaropes).
4. On the New Brunswick side of the Bay of Fundy, you can get a boat trip out of Grand Manan (ferry from Black's Harbour, NB) where you can take a boat trip to Machias Seal Island for puffins, razorbills, murres etc. Some of these trips land on the island and you have an opportunity to photograph the auks from a blind at close distances.
Thank You John.
We are in Perce, Photographed diving Gannets, two Minke Whales feeding. going to Bonnaventure Island in the morning.
Leaving for Digby, Nova Scotia on the 26th. Thank You for the valued info. Layton
