Today is the last day of my “bird photo blitz” for Vancouver Bird Week 2014 and for the Vancouver City Bird competition, for the simple reason that today, May 10th, is the final day of this special week and competition. So if you haven’t done so, take a moment to vote for you favourite Vancouver bird.
Today also happens to be International Migratory Bird Day 2014 – if you haven’t done so yet, I would strongly encourage you to explore this website.
I have chosen to finish my blitz with this beautiful pair of Tree Swallows checking out a tree house in Delta, BC’s George C. Reifel Migratory Bird Sanctuary. I chose this photo to make an important point about this week and day: Many migratory birds around the world are in great difficulty, especially if they eat insects on the fly. Although the Chimney Swift and Barn Swallow are doing far worse, Tree Swallows are also declining.
There are probably many reasons for the decline in flying insects and the flying birds that eat them, but the use of certain pesticides, the decreasing number of family farms and climate change are probably the three leading causes. This decline has been going on for some time (for three decades or maybe more) and is quite alarming; you can find out more here, here and here (and this is only a very small sample, by the way).
