Dr. Harry Vogel, senior biologist and executive director of the Loon Preservation Committee, tells WMUR-TV (http://bit.ly/18cdZTR ) that 153 of the threatened birds hatched statewide this summer, down from 170 last year.
He says 115 survived, down from 134 in 2012.
Vogel says the adult population remained stable at 283 loon pairs. That number has been right around 280 for several years.
Committee staff observe the birds throughout the summer before the birds fly out to the ocean or go south for the winter.
