Last week in the Vancouver Sun paper, I read an article on the decline of swallows in the Metro Vancouver area. (Tuesday, August 6, 2013). Apparently, swallows have been decreasing in numbers for decades, both regionally and nationally. The article cited several causes for the distressing situation, including the reduction in the numbers of insects through the widespread use of insecticides, the increase in pollution in urban areas, loss of traditional nesting sites and of course, climate change. Reduced access to food. No where to nest. Toxic chemicals. That’s quite a line-up of stressors.
The statistics are dismal—barn swallows, the most common species in Metro Vancouver, have declined by 70%, cliff swallows and purple martins by more than 50%:
“And there is little hope for recovery in the absence of decisive action,” said Derek Matthews, chair of the Vancouver Avian Research Centre.
I’m noting this article, not only for the fact that I’m interested in the birds that form part of the ecological environment of my community, but also because my project on bees includes the animals, insects and other predators that count bees as part of their food sources. The interconnection between various creatures is complex, and singling out just one from the many, would not address the reality of existence for those creatures. When I read this article on swallows, I realized that there before me, lay the evidence, a reciprocal, interdependent line of connection between the bees and their environment. Alas, interdependency means either life for all, or death for all.
