Lorraine Glass photographed these birds in Bowmont Park in Calgary on May 18.

The Killdeer may have been nesting right by a busy pathway. They lay their eggs right on the gravel, but the eggs are very hard to see, and the parents are really good at not giving away the nest location, and at distracting predators.

The Osprey is carrying material to line the nest, even though they probably have already laid their eggs. Ospreys will often add to the nest throughout the summer.

This appears to be a recently fledged chickadee, begging for food.

House Wrens are back in the city in their usual huge numbers. You can hear them singing all along the river valleys and in many residential neighbourhoods too. They have a big voice for such a tiny bird.
