Pigeons have navigational abilities so extraordinary they amaze Humans and Fey alike. The difference, of course, is that where Fey explain it simply with "It's Pigeon Magic!" Humans always feel the need to dig deeper, and have spent great effort in figuring out how pigeons do it. They've studied the brains and eyes of pigeons, and tracked them with GPS receivers, and bombarded them with magnetic pulses. That's just a thing Humans do. But hold on to this for a moment.
Flea's first spies reporting in are pigeons, a flock of them, and they gather around. A few scout out the ground: perhaps Flea has been thoughtful enough to scatter crumbs, so that any passing Human would just see "odd woman feeding pigeons" and think nothing of it.
"It's a terrible place," one pigeon says. "DON'T GO THERE."
"Tell her, Tony," another pigeon says.
"Yeah," agrees a third.
The pigeon smooths a few feathers. "Foist, you said this was a museum? Ain't no decent museum, I can tell you. I been to museums, and you know what they got? Food carts, outside, serving up hot dogs and stuff. None of that here. Not even any packs of little Human kids coming out of those yellow buses. You know, with the lunch bags and the lunch boxes, and right on cue all the little slobs gather in a picnic area and start to eat... and one starts a food fight and soon the buffet is on the floor for every pigeon..."
"Tell her about that time at the Metropolitan Museum of Art with the Twinkies!" a bird says.
"Yeah, that was.. that was freakin awesome. Man, I was stuffed. That kid brought like a whole case, but it fell and... hey, no, I'm supposed to be talkin bout this place. Don't distract me, Angie.
"Anyhoot, this utter and inexcusable lack of lunch is one thing, but... lemme see if I can explain. There's thing thing pigeons feel... hear, but it's not hearing. Just,it comes to us. And it comes from everywhere, and we just like different places have their different smells, they have their different... whatever this is. Humans don't ever get it, I think, but we do. But this place... lemme tell you, I've flown past this place before. It's different now. I can't tell you how, there's no words for it if you're not a pigeon. But something changed. That doesn't happen very often. Places are places, they keep feeling the same way. Things would be pretty screwed up for pigeons if they changed, right?"
