is this bird okay?

it was staying still, opening and closing its beak incessantly, and yet not making any noise. i found it on my porch when i came back home from school. i tried giving it water, kept a close eye on it, but it didn’t move at all despite the rain. it kept doing this for like half an hour, possibly way more since i don’t know when it got here. unfortunately i do need to leave the house so i can’t monitor him for the time being but i did move it into a cardboard box with some yarn and seeds to try and make it comfortable, im not sure if this is serious but i just wanted to reach out in case. i did leave a message to the local wildlife rescue. this is in canada, and i’m pretty sure it’s an american robin.
