heron

I live by a common and we have a heron who comes every year usual spring and winter .He/she has come to my garden few times as i have a pond(no fish) but i also have a heron ornament with outstretched wings near the pond.

The heron has started to sit on the fence of my garden and seems to be staring at the heron ornament. They have done this a couple of times .

I know this is probably a silly question but is the heron believing the other one is real?

also should i remove(the ornament) it as i do not wish to cause it any distress if it thinks its a potential mate?

Thoughts please.

Thank you
