The Beaver Pond Loop is probably the best, easy bird hike on the east side of the park. Hey, you don't even have to pay admission to the park because the trail head is before you reach the entrance. I cover this trail in "Glacier is for the birds" and on page 72 I mention that continuing on toward Red Eagle lake is one of the best locations to see Northern Hawk Owl. This was true again during the summer of 2018. Within a mile of the beaver pond loop junction on your way to Red Eagle Lake might be worth a look...There's lots of good birding as you continue toward the lake as well.
