Males feathers are very well developed and bright red & orange - base of bill a very deep reddish purple.
About 5 p.m. caught the No 7.- he really outsnapped- the No F went in the trap with him but she was released.
This legs area bright lemon yellow green - the iris is blood red his bill is ivory, extremely smooth - his temper is extremely vile - his bill is pied with a reddish-black marking.
His shield is somewhat more extensive than the female's and is very deep blood red whereas hers is a lighter almost orange-red. - while chasing some of the N brood warded young 2 of them at least took flight and did so well- they are fully capable of leaving the lake & believe.
