King City has been home to a Great Blue Heron heronry for decades. It is located in the southern part of King City, in a hardwood swamp at the back of the old Rumble farm. Bruce Rumble told me a couple of weeks ago that 30 or more years ago there were 30 to 40 nests occupied in the heronry. As King City has grown and people have encroached on the site, which is now owned by land developers, the herons have made themselves continuously scarce. Two years ago I found only one nest being used and last year, none.
Good new, though, as there are at least 10 nests in use this spring and there may be a few more, but I wanted to keep my distance and disturb the nesting birds as little as possible. Who knows why the resurgence in interest at this location? It's great to see the return of the Great Blue Herons and the site is protected by the Township of King through designations as an Environmental Protection Area and as an Area of Natural Scientific Interest, as well by the the Oak Ridges Moraine Act. Now that sewers are being installed in King City and the village will double in size over the next 10 to 15 years, one has to wonder about the future of King City's heronry. In the meantime, we'll enjoy it while we can. I hope you enjoying the spring migration.
