Using bird as indicator animals is hardly a new concept for humans. Coal miners famously used canaries as a warning of dangerous conditions, as scientists use them to warn us of problems in natural systems today. Birds are often sensitive to changes in the environment, and changes in bird communities are often the first symptom of fundamental changes in a given ecosystem. With this in mind, one of the first things The Phoenix Conservancy does with each new project area is conduct a survey of the bird species present. This gives us a starting point to measure the effects of our restoration work, and to monitor the progress of a regenerating ecosystem.
We recently conducted our 2018 breeding bird survey for Smoot Hill, and I never cease to be amazed by the difference that native prairie makes on the number and diversity of the bird community. The riot of color, motion, and song that characterizes Palouse Prairie in June is simply astonishing, and the sight of the sun rising over Kamiak Butte as the Dawn Chorus of singing birds fills the air is too beautiful to fully describe. That said, one of the central values of The Phoenix Conservancy is that our efforts are guided by scientific data, so I’ll let the results of the survey speak for themselves:
Point Count 2 (formerly-plowed pasture grass)
Western Meadowlark (1)
Point Count 3 (native Palouse Prairie)
Bullock’s Oriole (4)
This lack of birds in a habitat is an excellent indication of poor ecosystem health, and is obvious even to relatively new birdwatchers. We were thrilled to have help with our bird surveys of Conservation Park this year, thanks to the first and second grade students of Palouse Prairie Charter School. The class immediately noticed the silence of weed-dominated sections of the park, in contrast with the park sections containing native plants.
So fun, in fact, that their absence is just as conspicuous as their presence. Even to a first grader making their first connections with the natural world, observing a weedy field without birds seems strange, disorienting. The question that arose from these young birders echoes one of the most fundamental signs of an ecosystem in distress, the warning that inspired Rachel Carson’s Silent Spring in 1962, and one of the most important metrics that The Phoenix Conservancy uses as we work to restore endangered ecosystems.
