Fox Sparrow

Any time we see snowfall from mid-March on, we might notice an increase in the number and species diversity of birds at our backyard feeders. Those who pay close attention might also have the opportunity to view more elusive birds – those that would otherwise just be passing through or returning to the area relatively unnoticed – that are driven out of their preferred habitats by the extreme conditions in search of food. One such bird that can seem to appear out of nowhere is the Fox Sparrow (Passerella iliaca). These large sparrows really enjoy scratching at the ground with both...

Conditions have to be just right to entice them out from under their chosen cover objects; a warm 40° night with rain sets the stage for spotted salamanders to begin their migration. Will we soon see the required circumstances to set this charismatic species on the move? Keep an eye on the weather and another on nearby pools and ponds so as not to miss the big...

Students will participate in a variety of research projects, including migratory bird banding and monitoring endangered and recovering amphibian populations, such as this Rufous-eyed Brook Tree Frog (Duellmanohyla rufioculis). Stay tuned for more information...
