Redhawk Caldera confused

"Towhee, Titmouse, Orca and Phox," Birk repeated the names, knowing very well that the next time he met one of the cubs, he would have a hard time telling them apart (except for Towhee, her scowl was hard to forget). 

"I heard that you have siblings too," he went one, recalling that, when he had last met Finley, she had mentioned them and she had been pissed off at one of them specifically. Too bad her (or his?) name had escaped him too. "What are they like?"
