Picture of the Week:
This photo of a Barred Owl was taken by Mike Houck in Washington Park and posted on our Backyard BioBlitz Facebook Page: Barred Owls were historically considered an eastern species but have moved across the Great Plains of Canada and have established themselves in British Columbia, Washington and Oregon in recent decades. Today they are one of the most commonly sighted owls on our urban landscape.
Tip of the Week:
Many ducks in the urban environment nest away from water. Many of our parks are over-crowed with other waterfowl as well as potential predators. Ducks will often find a quiet place away from water sources to lay their eggs—sometimes as much as mile. They can fly back and forth to the nest while they are incubating the eggs, but once the eggs hatch, they must lead their flightless ducklings to the water on the ground. It is not uncommon to see parent ducks leading a line of duckings across our urban landscape. While it is tempting to try and “rescue” the ducklings, please don’t. Often when people try to capture the ducklings, the parent flush (fly away) and the young scatter. The results is lots of orphans. The best thing you can do is to let them make their own way, or if you feel inclined to try and clear a path for them (ask people to step out of their way, stop traffic if it can be done safely, etc.) For more information on nesting ducks and ducklings, click here.
