Climate-sensitive bird hints at global warming’s lasting impact
It’s hard to be a bird these days.
Take the black-throated blue warbler. The migration patterns of this small songbird have been slowly but steadily changing over the past 50 years, according to a study published Thursday in the journal The Auk: Ornithological Advances.
The timing of the bird’s flight patterns has been advancing, with its spring migration occurring around one day earlier per decade. While the warbler isn’t facing the same risks as some of its other feathered friends, it’s the kind of small but unignorable change that ornithologists are becoming all too familiar with.
Birds are very susceptible to changes, and they are really good indicators of what’s happening around them in their physical environment. This has made birds a particularly important part of understanding the growing impact of climate change.
