Small Tree-Finch - Introduction | Neotropical Birds Online

Pretty positive I saw one in our neighborhood today with other finches . Very small , almost like a large humming bird but the blue was so intense ,it was almost like a black /purple color .

The Laysan finch () is a species of , that is to the . It is one of four remaining finch-billed Hawaiian honeycreepers, and is closely related to the smaller . The Laysan finch is named for , the island to which it was endemic on its discovery. It was subsequently introduced to a few other , and its historical range included some of the .

I also have 2 blue black grassquits on my finch feeder with all the gold finches. I too thought they might be blue grosbeaks but much too small definitely same size as finches. I live in Daphne Alabama.

The already smaller-beaked medium ground finch couldn't keep up with the newly arrived large ground finch, which is about twice as big and dominates feeding grounds. The first thing you need to know about keeping finches, such as zebra, society, or spice finches is that you cannot keepa solitary bird. These small finches don't thrive when kept alone. You must keep at least two finches or your finch will probably not survive, and at the very least, will be a very unhappy bird.Few people have the tenacity of ecologists , willing to spend part of each year since 1973 in a tent on a tiny, barren volcanic island in the Galapagos. Even fewer would have the patience to catch, weigh, measure, and identify hundreds of small birds and record their diets of seeds.

But for the Grants, the rewards have been great: They have done nothing less than witness theory of evolution unfold before their eyes. That would have stunned Darwin, who thought operated over vast periods of time and couldn't be observed.

In their natural laboratory, the 100-acre island called Daphne Major, the Grants and their assistants watched the struggle for survival among individuals in two species of small birds called Darwin's finches. The struggle is mainly about food -- different types of seeds -- and the availability of that food is dramatically influenced by year-to-year weather changes.

The Grants wanted to find out whether they could see the force of natural selection at work, judging by which birds survived the changing environment. For the finches, body size and the size and shape of their beaks are that vary in adapting to environmental or changes in those niches. Body and beak variation occurs randomly. The birds with the best-suited bodies and beaks for the particular environment survive and pass along the successful from one generation to another through natural selection.

Natural selection at its most powerful winnowed certain finches harshly during a severe drought in 1977. That year, the vegetation withered. Seeds of all kinds were scarce. The small, soft ones were quickly exhausted by the birds, leaving mainly large, tough seeds that the finches normally ignore. Under these drastically changing conditions, the struggle to survive favored the larger birds with deep, strong beaks for opening the hard seeds.

Smaller finches with less-powerful beaks perished.

So the birds that were the winners in the game of natural selection lived to reproduce. The big-beaked finches just happened to be the ones favored by the particular set of conditions Nature imposed that year.

Now the next step: evolution. The Grants found that the offspring of the birds that survived the 1977 drought tended to be larger, with bigger beaks. So the adaptation to a changed environment led to a larger-beaked finch population in the following generation.

Adaptation can go either way, of course. As the Grants later found, unusually rainy weather in 1984-85 resulted in more small, soft seeds on the menu and fewer of the large, tough ones. Sure enough, the birds best adapted to eat those seeds because of their smaller beaks were the ones that survived and produced the most offspring.

Evolution had cycled back the other direction.Also, make sure the bar spacing of your finch cage isn't greater than ½ inch apart. Finches are small birds with small heads and they can get their head stuck in betweenthe bars, or even escape from the cage, if the bar spacing is too wide.
