Not having neither the time or the energy to put much thought into a post, I decided instead to share some unrelated photos.
I was a little surprised to see Great Blue Herons building nest during my early March visit to Middle Creek. The rookery was too far away from the road to allow great shots and getting any closer was unlawful so I had to be satisfied with what was available. Shooting with the 600mm lens I could see from viewing the camera LCD that the shots were soft. Resorting to manual focus and using live view at 10x zoom the resulting images were sharper.
These mallards may look no different than your friendly everyday park ducks but they fully understand the dangers that humans present. The nearest hen has already spotted me and at the first click of the shutter they exploded into the air.
