As regular CFZ-watchers will know, for some time Corinna has been doing a column for Animals & Men and a regular segment on On The Track... particularly about out-of-place birds and rare vagrants. There seem to be more and more bird stories from all over the world hitting the news these days so, to make room for them all - and to give them all equal and worthy coverage - she has set up this new blog to cover all things feathery and Fortean.

Why Elk Are Robbing Birds

Plants and animals in a given area form an ecological system of interacting species. Impacts on one, or just a few, species can ripple throughout the system and have indirect effects on other species within a larger community.

Many plants and animals are sensitive to shifts in temperature and precipitation and subsequently relocate to more suitable climates or reschedule their seasonal activities. 

One of the most challenging tasks facing ecologists today is determining how species are responding to rapid changes in climate, and the consequences. In the high-elevation canyons along the southern edge of the Colorado Plateau in central Arizona, I worked with my colleague Thomas Martin of the U.S. Geological Survey to study how more than two decades of changing winter temperatures have hurt spring breeding success for birds. This harm results not just from changing temperature, but stem indirectly from climate impacts on elk, small predators and even the forest the birds inhabit.
