Thanks Philip. I wondered about the “carbuncle” and when it would
Start to grow. I wasn’t aware the bill color might deepen so.
I noticed a dark spot on Maxey birds Bill where too and bottom mandibles
meet. Not sure if it is a discoloration or divot or speck of mud but
couldn’t
See anything on the other phots from lake 6.

There did seem to be a small dark spot or divot at the Mac

Sibley puts the timing of the knob at February to June. We don’t usually get
to see them on our wintering birds.

breeding season, there is a laterally flattened "horn" on the upper bill,
located about one-third the bill's length behind the tip. This is the only
one of the eight species of pelican to have a bill "horn". The horn is shed
after the birds have mated and laid their eggs. “
Logic dictates that if the knob is shed after breeding, at some point it
grows back. The bare parts also get more brightly colored during breeding
season. So, who knows? This is the the time of year when birds start
moving around and putting on their breeding finery. Part of what makes
birding fun.
