Can birds "converse" with other types of birds?

I was just watching a crow and a broad-winged hawk perched together on the top of a tree, a few feet apart. They were facing each other, with what really seemed like a clear back-and-forth type dialogue. They honestly reminded me of two strangers sitting at a bus stop having a friendly conversation. 

Am I anthropomorphizing a coincidence or could they actually have been having a conversation/dialogue?

songbirds will often make raspy, hissing sounds whenever there is a threat in the area, which other species can understand as a threat and respond to. Try this: go out to a garden or somewhere that birds are common, and repeatedly make a “pssshhwssshhwssshh..” sound. This is called pishing in the birding field. Notice birds will likely come out to see what is going on or vocalize back to you.
