This is the look you get when you try to nest too close to Momma Blue Heron. Momma is not tolerant at all! I think I've seen that look before... At Wakodahatchee Wetlands.
The mating pairs are extremely intimate while building their nest. The male preens the female while she works, and there is a lot of cuddling during breaks. Viera Wetlands, Melbourne, FL.
