Special interests in nature- does anyone else have this?

Hi,

Although I'm an astrophysicist, I have a huge interest in nature in general. I've been known to travel for hours in order to see something very rare and unique in the UK (and periodically planning things outside of the UK). It used to be traditionally birds only, but has now expanded rather significantly to take into account other plants and wildlife. 

In the past, I have been known to:

1) Obsessively search all over Windsor Great Park for a very specific, poisonous fungus (Rubroboletus legaliae) I absolutely, absolutely required on that trip because I once saw it in a book when 7 and liked what it looked like. I searched nonstop for over 4 hours until I found it. 

2) Walking around in circles in Thetford Forest in a specific site for hours (including under the rain) until I saw a goshawk. 

3) Travel as far as Kilnsey Park in a day trip to see lady's slipper orchids, in the context of my phone being smashed on the way there and me being left without any navigation at all when cycling in the Yorkshire Dales

Today my brain was running in circles because I managed to figure out where the wild Catacol whitebeam was growing on the Isle of Arran, adding it to a growing collection of rare plants and other 'nature things' which I currently have. I ended up becoming overwhelmed, shutting down and being barely able to function for a few hours. 

I was wondering, does anyone else have this? Are you interested in nature?
