[They smell like bird, but not quite, dude, and Patrick leaves the offerings at first, trying to step around them and not disturb their righteousness on their home turf. He knows they were left there, and it's obvious that they aren't related to nesting, which is happening all over the Repose woods this time of year. Dude, it's like porn central out there, but this is different. He leaves them until he has time to crouch on the top step and sketch them.
Then, dude pulls the chronometer out of his pocket and tries to see what left them there. Full disclosure, my dudes, but the chronometer usually takes him to whatever unearthly layer houses the elvenwood when he's in his wood. But this feels like Newt-level shenanigans, and he tries it. He opens the chronometer and looks through the pane, just to see what he can see.]
