Identified by nasally “cah” compared to the louder, harsher cawing of AMCR, which also vocalized for comparison. Could see smaller size when AMCR was nearby for direct comparison. At first we just saw two, both of which were calling and scavenging from a garbage can. Eventually they both started calling a bit more intensely and soon 6 more flew in and began calling as well. Can't say with certainty all 8 were calling, but they were all near each other and appeared the same size. Two AMCR also flew over and called, but never landed with the FICRs.
