In my post last week, I had to re-edit to mention that I actually did see a white-breasted nuthatch on our trees and at the feeder. I was probably so excited to report it that I mistakenly edited out that part.
This week, a news item just out reports that the Fender’s Blue butterfly numbers are up at a large reserve near Eugene in the Willamette Valley. Many have rallied around this small, but charismatic species. Unlike the nuthatch and acorn woodpecker, the Fender’s Blue is on the endangered species list. (The birds are slowly sliding toward it in some locales, but their numbers are still up).
A thought or two about insects: perhaps they can recover more quickly than some species (i.e. the spotted owl, mentioned in the article) because their populations have a quicker response time, or because their territories are smaller and more easily managed.
Many things going on there – they don’t have the competition from bigger more aggressive species like the spotted owl does. Insects also tend toward boom and bust cycles because of weather, food, disease and such, although some more than others (think aphids – at the bottom of the food chain and also designed for rapid reproduction). If their numbers drop, or rise, it may depend on environmental conditions other than the management strategies that people are using.
Nevertheless, these strategies are undeniably beneficial. It does one good to start the year with positive news. Maybe we’ll have some Fender’s Blues on our place soon. We have a patch of their larval host plants, some nectar sources, and it would be great if the Conservation District would decide we are worthy of burning the fields! I’m still pestering them about that…
