Ditto,
When I was a fishing fool in public waters (public waters are inferior to my ponds now so I dont' go much
) I noticed males only on the beds more times than not. In fact, when fishing for them in New England where they are considered trash fish, I have caught over 100 off the beds with not one being a female. Just as with the largemouth bass which is in the sunfish family it's entirely possible the females only show up briefly.
BTW I no longer wipe out colonies of bluegills as I know better. However in New England there is no competition as the locals would rather catch a 10 inch stocked trout vs. a 10 inch bluegill.
I simply answered Marc Z's question in regards to it being possible many of his males were hybrids -- that is if he had hybrids in the pond.
Marc,
Did you plant hybrids exclusively? If not, then it's highly possible you have regular males on their nests.
