I visited Carleton Park twice last week (and thank you again for the tip) and must agree: it's a lovely little spot. A small neighborhood park that feels secluded and sweet. Quite small too, so that it's very easy to walk back and forth from one end to the other...
I've yet to visit the park in the early hours of morning, but have been there on two occasions from 6-9 pm. I've seen plenty of cedar waxwings, a few woodpeckers, several cardinals and nuthatches, and quite a number of lovely robins with spotted bellies (juveniles?) but I've yet to see any Northern Flickers, and the mysterious green heron has eluded me also...
The idea of seeing a green heron in a Brampton tree is so exciting to me, but perhaps the fellow only visits in the mornings?
Anyhow, if anyone else has seen Mr. Green or any flickers, please let me know...the park is worth a visit just for the waxwings and the calm and restful feeling that will gladden your heart when you sit and watch the trees, if you ask me...
O and I almost forgot: my birdwife and I were watching the trees when all of a sudden a great blue heron flew over our heads! With our cheapo telephoto lenses we were able to get a few decent shots...
