Tree Swallow

Flora and Fauna Friday: Tree Swallow

My Flora and Fauna Friday post this week is the Tree Swallow (Tachycineta bicolor), a member of the swallows and martins family found in the Americas.

This individual was photographed at Isaac Lake on the South Bruce Peninsula, Ontario last spring. The species traditionally nests in tree cavities but will use nestboxes. There are several areas at Isaac Lake with groups of nestboxes for them.

This is also a contribution to Becky’s July Squares: Trees photo challenge.

I first photographed them in Saskatchewan in the mid 1990s. Out there people put nest boxes on fence posts around their houses. The swallows then eat hundreds of mosquitoes helping reduce the numbers.

It’s been a strange year for mosquitoes and bugs in general. We had a very dry spring so mosquitoes were very scarce. Summer has been very wet with large temperature variations. In the hot spells the mosquitoes are terrible. In the cool spells they disappear.

The black flies we get in spring were around for a very short period this year. Not a bad thing as I react badly to their bites not having grown up and developed an immunity to them.

You may not do well with black fly bites then. I come up in small blisters that drag on for days. I know life long Ontario residents that still have a nasty reaction to the bites.

Having natural history photos from both Europe and North America means that there’s usually a percentage of readers who aren’t familiar with a species.
