Both Durand and Matrix have now been observed on the ledge, together. The video on the Bird Cams Around the World (BCAW) Site shows Durand on the ledge this morning, and Matrix comes swooping in and lands on the Cam. She heads straight for him making lots of noise, and I could not tell if she was saying get off of there before I tear you apart, or hello, handsome, where have you been all my life, but, anyway, she continued with this just below the Cam, and he seemed to be listening, so I don't know if she was telling him what she is looking for in a man or what, but shortly thereafter, he revealed that he had a treat for her, and then he took off with it. I think this piqued her interest. Later, they are again both on the ledge, so I think they are beginning to establish a routine.
