Any time anyone wants to go I normally go out every afternoon. I carry my kayak in my truck most of the season and can be on the water by 2:30-3:00 the latest, but its the last 10-15 min is when he action starts.
I hunt in the Sturbridge area, few key points. 1, if you don't have a hunting Lic you can go and watch but can not help in anyway, 2, your CCW will need to stay in the truck, as a game warden might say we used it to shoot a duck. 3, If you do get a Lic and decide to hunt, A, make sure you complete your HIP info, B, you have a your FEDERAL duck stamp, C, you have your plug in place in your shotgun to only fire 3 rounds ( one in the chamber two in the pipe )
After all that at least try to know some limit laws, so if asked you kinda sound like you know what you are talking about. Ducks in general are easy to spot over other birds, and yes its good to know limits but to limit out in one afternoon ( although its been done millions of times ) its not something pulled off every time out.
Mallards and wood ducks are easy to ID after a few times out, so if you limit on one type of bird I just sit and enjoy them flying by, tells me my cover is still good if they are still flying by me lol. Geese, ( aka rib eye in the sky ) are so easy to spot and ID, they are huge and grey, make enough noise to let you know what they are.
Gear, good boots that are warm and waterproof up to your knees or so, you will be standing in some shallow water ( 2-3"s most of the time ). Some camo, or gear that matches the area you hunt in. I went in my work pants one time, tan Carhart pants, got two ducks that day so I guess they didn't spot my non camo pants lol.
Waterproof jacket or good rain gear that's black, ducks have a keen eyes, but if your cover is good they might spot you at the last second, buy then your shooting at them anyways.
Over cast days are the best, at sunset its all over, no more hunting not worth even tying to take a duck after that time, if the warden see's you its not going to be good for you.
But when its a over cast evening the ducks start flying in early than normal and you end up with maybe 15 min of better hunting than if it was sunny. Sun set time is still the time to stop just with over cast the ducks start flying early cause they can't tell time lol.
