Green Heron - Juvenile

I'm not sure why, but it seems whenever I see a juvenile Green Heron, they tend to have their necks fully extended. You wouldn't know that Green Herons have such long necks from typical adult sightings as adults seem to always have it retracted. Maybe its just because juvenile birds tend to be more curious and trusting than adults, so they just want to see whats going on around them.
I saw this juvenile at Fernhill Wetlands back on Sept 9. I had to creep down through the tall grass to get a clear view of it as it stood along the shore. I saw another similarly extended necked juvenile here a year ago this past August. Here's a couple of examples of adults with their necks retracted; here and here.
