The call of the common loon evokes wild Montana. Montana has about 56 pairs of common loons, less than half successfully nest each year, producing 1-2 chicks per pair. Part of the problem is that nesting loons are easily pushed off their nest by boats that approach closer than 140 yards. If the boat lingers in the area, the eggs or chicks may be lost to cold temperatures or bird predation. The tremolo call and approaching loons usually indicate you are too close and should leave the area.
The Montana Loon Working Group and Montana FWP post floating bouys around nesting areas, advising boaters to stay clear. Montana Loon Society president Lynn Kelly and Flathead Wildlife president Jim Vashro along with Sandi Vashro and Susan Kujawa posted bouys on Island Lake west of Lost Trail Refuge. Island Lake has 3 nesting pairs, one pair was already nesting. The narrow elongated shape of the lake, along with recent shoreline residential development make it challenging for nesting.
Also of note, the strong wind storm in December laid down acres of trees around Island Lake. Residents on one road had to be rescued by Search and Rescue personnel with chain saws.
