Are they there year round or certain times of year?

They're there year round, but will only come out if it's warm enough ( I think above 65 degrees F).

Visit just before sundown.

I think year round. We have seen them in Jab, Feb, and March. No reason for then to leave in summer months, I dont think.

Indeed, year-round when it's warm. No doubt they will come out tonight. They come out and mostly head in the direction of Lake Alice.

Yes, Florida weather allows that
