Being from Mayo, I would definitely say the Atlantic Salmon or the Red Grouse. What would you say about your own?
Edit : Wild animals preferably, native or introduced, but still species living in the wild. Nothing extinct or living in zoos or sanctuaries.
I've been doing a wee bit of personal research into what species live on my land, the garden, river, and the lakes up the road. I have a small field that I leave wild. Here's the amount I have.
37 species of birds live around here/migrate here. 38 if you include the gulls that arrive during silage season.
8 species of butterfly (could be more as more species will only appear later in the year, but that's from what I've noticed over the last few weeks).
11 species of mammal (between the field and the river).
8 species of freshwater fish.
2 amphibians.
And an absolute rake of insects.
Most of these species tend to be collected on my wee field and spill over into my garden. My field is like an island in a green ocean of silage fields. There's a mix of native trees like hawthorne, willow, elder, and ash to non natives like palm, pine, horse chestnut, and cherry lorel. I started by cutting out some lorel so it wouldn't choke the place. Planted some wildflowers sporadically and then just left it to its own devices. Species just started appearing over the last few years. I do know there are more butterfly species, I just haven't properly got a chance to identify them yet. St. Marks fly hatched a few days ago, and the birds are in full swing, trying to eat them. It's amazing that this once barren field became a small refuge for smaller wildlife species.
If only I had 1000 acres to do the same on 😅
