Recently we released the American Bitterns that we had raised from chicks. We had to be very careful around them, not letting them see us. Feeding them when they were small meant lifting the cover over their shorebird box and using a bird head puppet. I cut up mice for them, which they seemed to appreciate. When they were fully feathered, they were moved to one of the outdoor aviaries.
We released them not far from IBRRC. There’s a creek with trees that runs along Wetlands Lane. Here’s a picture:

It is the last car in the row with the red car, right next to the rosemary bushes. Our building is huge, but it sure looks tiny in this picture. The building is near the top of the picture.

The nest consists of a pile of reeds, sedges, or similar plant material available nearby and is built by the female alone. Breeding season begins in late April to May and ends by late July. Two – Five eggs are laid. The female incubates the eggs, beginning with the first egg, for 24 – 29 days. Eggs hatch over several days and young differ in size. Nestlings are semi-altricial and downy. The young leave the nest after about two weeks and are tended nearby. Age at first flight and at independence not known.
