Interim Vice President for Instruction Peter Lortz calls our attention to the start of spring and frog calls in the air.
"Now is the time for one of the amazing natural events on North's campus as the annual chorus of the Pacific Tree Frogs (aka Pacific Chorus Frogs) has begun.
"North has what is considered by many to be the largest breeding population of Pacific Tree Frogs in urban Seattle - right here in our own wetlands. This is their breeding time. You can hear the awesome chorus in the greenbelt. It is actually loud enough to drown out I-5. If you would like to listen, they are most active at dawn and dusk; and the north end of campus is the best place to experience it.
"Males head to the ponds in the wetlands, and, once they get there, they start calling for the females. When the females get there, the breeding begins. Eggs get laid shortly thereafter, and tadpoles live in the ponds in the early spring."
