These two juvenile night herons looked very cute perched together on this old stump, but they were quite far away.
Previously, I would not have bothered taking their photo since I was limited to 400mm,
but with this new setup they are almost 3 times larger to the camera.
I think it turned out quite nicely, especially considering ISO 1600 and 1/100 shutter speed.

Taken during my first outing with new Sigmonster lens and 1D Mark III camera.
More images taken with this lens can be seen here.
