Robins, like crows and ravens (and surely other birds--I'm not an expert) REMEMBER FACES/DOGS.
The trees instantly explode with hostile tweets every single time I take Sooki out now--but not Piggy! So, yeah. They know...they remember. o_O (How creepy is that?!)
Last night (still light out) poor Soo was trying to poop and one robin kept scream-tweeting and I kid you not--dive bombing her. It kept getting closer and closer and I so worried it was gonna peck at her (it frigging knew she busy and couldn't move...it wants revenge).
Just thought I'd share!
