Not sure I have enough information for ID help but here is what I saw. A hawk soaring (circles maybe 4 times) at a distance (but saw with binoculars) out of apartment window and it is a clear but sunny day. Saw mostly from underneath, but seemed light brown/bronze on top and appeared to flash a white patch on lower back or above the tail. Underneath I could only see white overall with darker wing tips and what appeared to be two dark vertical (in line with body) marks in the middle of each wing. I could not see any markings on the tail. Any help would be appreciated. Thanks!
