Never Bowhunted them, but I also did hunt on the Eastern Shore (near cambridge) for Sika growing up . Alot of fun, and good lord I love to hear them "bugle". It's like our " North american" elk, but more of a shrill whistle. Tough to hunt- very nocturnal-and as BC mentioned they LOVE the swampy terrain. First year I ever hunted them, I mistook a few does for dogs and never shot
60 pounds was about average for a doe as I recall- bucks about 80 pounds.
There are two types of animals- SIKA, and SITKA- they are totally different. The ones on MD's eastern shore (Sika) are an asian Elk and were supposedly an accident- A large group of them were washed ashore around the turn of the 19th/20th century when a cargo ship carrying them wrecked/sunk- which is also what happened with the wild ponies on Chincoteague Island. THats the story I was told by a resident of the area when I was young-not sure if it's 100% Gospel. Maybe someone else has the scoop?
Anyway- tons of fun! I'd love to go back and just hear some bugle
