Blackwell Trail Butterflies + 1 Bird:

A few years ago a friend found some Silvery Blue butterflies flying at Blackwell Trails Park. To the best of my knowledge, this was a first for the area. They are common throughout most of Canada and are starting to expand into SW Ontario. It is a species of glossy blue butterflies that are exclusively found in North America.

At first glance, this butterfly appears to be similar to the above Silvery Blue. However, it has a tiny hair-like tail and a couple of orange spots on each hind wing. I don't often get to see the blue upper wing of the Eastern-tailed Blue. 

Sulphur butterflies are also flying including this Orange Sulphur.

Another treat was finding a Red-headed Woodpecker which appears to be nesting! The endangered Red-headed Woodpecker has been named the official Bird of the City of Sarnia! Bird Friendly Sarnia conducted a poll in which members of the community voted for their favourite bird.
