Search Engines and Male Moluccan Cockatoos

I tried Rollyo, Mamma, and Dogpile, searching for articles about Moluccan cockatoos. In Mamma I found a wonderful article about male Moluccan cockatoos titled "Magnificent Male Moluccan". I also like the concept behind Rollyo - creating your own customized search engine, or searchroll, which can eliminate a lot of unwanted information from websites you don't really care about.
