Seagull in Lagos

I stayed 2 days in Lagos. While I wasnt scootering all over Algarve, i spent the two evenings eating roasted chicken picked up at the local supermarket. As i layed on my bed with the chicken next to me, this seagull showed up at my open door. I was bummed i had no bread to toss it. But then i was curious if he would eat the chicken bones after i was done with it. I wonder if it would be like canabalism for birds. That seagull proceeded to swallow just about every bone from the chicken! The next morning, he is there ar my door for more. I decided to get roasted chicken again that night, to the delight of the seagull i am sure.
