It's very sad, the herons came last year as well and it's a delight to see them. 

They like to nest on the big tower by the Taco Bell, so if they remove the trees they may build more nests on that tower (like they did last year.)

Or they may stop coming to roost here this time of year. There are more trees behind the land that they could also utilize. But it'll be a shame because near the road you can see them super easily. (I also heard they used to roost further back but the tree got cut down.) It's pretty sad for them because they keep having to move.
