During summertime outings, muted, loose-fitting clothing works best. This stuff is cool and great for insect protection. We usually don't have to fight insects. Folks who are sensitive to mosquitoes and black flies can pack repellent or wear long sleeves and pants in muted colors and perhaps a bandana around the neck. The Rewards of Patience Finding and actually seeing birds through binoculars takes some practice.
Nothing is more effective at scaring away birds than sudden movement.
Even raising binoculars to your eyes can startle a songbird nearby and send it off into the woods. The skilled birder moves slowly, wears muted colors, speaks in a low voice and keeps a respectful distance. When you spot the bird with your naked eyes, lock them on the spot and slowly raise your binoculars. If you don't see the bird immediately in the binos, don't try scanning the trees. Lower your binoculars.
