#1 (lifer) - Heard it before I saw it.
#2 (lifer) - Beautiful. Bird of the day for me for sure even though I know they're common around here. Saw four of them on the small lake I was working on.
#3 - Just making sure.
#4 - Again just making sure
#5 (lifer) - Best shot I could get! They really didn't want me to get close.
#6 - This one had me stumped in the field because it was so far up and I hadn't learned their call yet. I think I have the ID now though.
