PORTLAND, Maine — More than 900 people are heading out to Maine's lakes and ponds to participate in the state's annual loon count.
The Maine Audubon loon count takes place at 7 a.m. on Saturday.
The group estimated that there were more than 3,700 adult loons last year. It says that its estimate of the adult loon population in the southern part of Maine has increased over the last 31 years, but the numbers have also dipped several times over that period.
Last year, the estimated chick count was 324. That's more chicks than the year before, but fewer than 2011. Maine Audubon says the estimates of loon chicks vary dramatically every year and haven't followed the same trend as the adult loons.
