This Red-winged Blackbird was upset by a Great Blue Heron nears its nest and made a determined effort to drive it off. The heron stood its ground as it seemed to have found a productive fishing spot. In between forays, the heron grabbed a number of small fish.
The Peregrine Falcon, Falco peregrinus, is one of the most exciting birds to watch in the world, especially when it chases its prey at speeds of 200 mph (320 kmph).
It breeds widely, in fact it can be found everywhere but the polar regions. It has suffered breeding failure due to DDT contamination but has made an excellent recovery after that chemical was banned.
This increased breeding success has happened here in Ontario with a good number of pairs raising young birds. They prefer tall man made structures like buildings and bridges, especially if there is a supply of pigeons nearby.
