The eloquent wingspan of a Tern

At least I think it's a Tern of some kind.. It's been a lovely day. A walk along the river to the lake, going to the birders candy store for another feeder (never can have enough), spending time with my dad (45 minutes of chatting) and now relaxing until an early bedtime before heading to the Tri-Cities. If all goes as planned, it'll be and easy 500 miles day..
