Raven feast!

Few blocks away from my house, a party was organised the night before. Music blasting through the air. I did not get enough sleep and of course i could not go for it. it finally subsided few hours later.
The next morning, going for my early morning strolls( not regular)- an attempt to also see what mess the party freaks had made the previous night, i found a number of ravens, say about 12! surprised, i approached them for a clear shot- they all flew away.....arrgh..it pained so much. Determined to have my shot, i stuck around hoping at least a few will come back....i was right.
I sought to find out why they all gathered there, probably for their own feast!- i found crumbs of food particles on the ground- i figured.
