It's all about ecological niches. Different islands had different exposures to wind and sea, different surface areas, different elevations, different resources, different sets of competing flora and fauna. In short, each island represented a different environment to which the common ancestral species of finches which first populated them had to adapt and optimize to for purposes of survival. Thus, islands with trees offering thick seeds and nuts as a food source presented a prime niche to those finches which developed thick beaks for cracking those shells, while islands having long, slender blossoms as a potential food source favored those finches born with progressively longer and delicate beaks. In was this diversification of survival opportunities to successive generations of diversifying finches which drove specialization and subsequent speciesation of the ancestral finches to the point that Darwin did not even realize they were all finches until he was so informed after his voyage was over. That is how much the fourteen species had diversified over ancestral time on those islands.

Don't worry about them. They only come around for the free food. When you leave they will find other food, eiethr growing naturally, or from someone else who loves watching birds. We sometimes feed the birds here. We also put out food and apples for the deer that come up. If they aren't munching on free food they are browsing on the fresh growth and blackberry briars. Animals are incredibly resilient and resourceful. I am sure they will manage when you are gone. The important thing is to enjoy them during the rest of your time there.Avian Caretaker

so agreed with you! Leave those pseaonrl judgement to yourself!On the contrary, China has always held the reputation for raising children to the cultural expectation. Respect for parents is a first, nothing top that! I am soon to be a mom and I know that kids will be kids, but we are the adults to make sure they grow up to be responsible individual overall that IS my responsibility.
