I believed it was boring and weird ("Why can't they just goggle the bird?"). But I recently bought a bird feeder for my cat and I'm more invested in the birds than she is. It's like boring Pokémon, I love it lol.
Honestly, my husband and I birdwatch and we treat it like Pokémon Snap when we go out! Myself with binoculars, husband with camera.
I felt like it adds another dimension or another sense to our world. When I walk from parking lot to work for example, I can hear and identify what birds are around just off sound alone.
