I'd spotted loads of bucks in October and November this year. I'd created several short YouTube videos of them and included links to them in playlists "Eye-caught Snippets" and "Oh, deer!". In the last few days, I decided these October and November bucks warranted their own playlist.
As I'd run across so many bucks recently, I became curious enough to Google about bucks and antlers, particularly about growth spurts.
From "Antler Growth Cycle":
Antlers grow rapidly from their pedicle (base) while in velvet during the spring and summer, as fast as 3/4 inch/week for yearlings and 1 1/2 inches per week for adults during peak growth ... Growth rate slows dramatically during late summer while mineralization of the antler is completed.From "Whitetail Deer Antler Growth Process"
over a course of 120 days from late March through early August, a mature buck can grow in excess of 200 inches of bone on his head
This site includes lot of pix showing antlers by time of year. The video link points to "Whitetail Deer Antler Growth Timeline". Note the looks for October and November.
"Time Lapse Antler Growth of Whitetail Deer - See How Fast Antlers Grow" is another visually informative video.
