The whimsical sounds of the Birds, Ornithology and why birds sing, territory and more with Miranda Zammarelli
Description
Listening to the dawn chorus is more than just a morning wakeup call; it’s a data stream revealing the health of our planet. Dr. Jeffrey Zurek welcomes PhD candidate Miranda Zamorelli (Dartmouth College) to discuss the Hubbard Brook Experimental Forest and decoding the "territorial rap battles" of songbirds.
We explore the "wild laboratory," where watersheds are manipulated to see how ecosystems respond to change. Miranda shares how tracking the loud, dome-nesting Ovenbird helps us understand the environmental resilience of bird populations in a changing climate.
