The Medium Ground Finch is classified as Least Concern. Does not qualify for a more at risk category. Widespread and abundant taxa are included in this category.

populations and movement of medium ground finches and the effects of beak and head morphology on song and feeding. A high-priority project is protecting the last remaining populations of mangrove finches. Scientists are monitoring the finches and their mangrove habitat. Intervention to control the main threats and establishment of a captive breeding program are underway. This work is crucial to prevent the mangrove finch from becoming the first iconic finch species lost from Galapagos. Retrieved from "http://galapedia.darwinfoundation. More

Apparently in response, the medium ground finch evolved to have an even smaller beak, making the species more adept at eating small seeds that didn't interest the larger finch. "This is a phenomenon known as character displacement," Peter Grant said. "It is a very important one in studies of evolution, because it shows that species interact for food and undergo evolutionary change which minimizes further competition. More

finch but is in a mixed flock is probably a medium ground finch that is at the very large end of the medium finch range. Large ground finches are more solitary than medium ground finches. I photographed finch #1 at the tortoise pool at the Charles Darwin Research Station on Santa Cruz and there were lots of medium finches around that day. Finch #2 is definitely a large ground finch because I photographed it on Genovesa.. I always thought that Finch #3 was a small ground finch. More

in the case of the medium ground finch is intermediate between those of the other ground finches (2) (3). More

medium ground finch of Galapagos Islands off Ecuador medium ground finch lives on seeds, cracks them open via force of beak the Grant's studied finches on Daphne Major, an small island (800 sq. yd) in 1977 island had only 2mm of rain instead of normal 130mm... More

3) Medium Ground Finch: (Geospiza fortis) can be seen in the major Islands (Isabela, Santa Cruz, San Cristobal) except in the smaller ones like Espanola or Genovesa. 4) Large Ground Finch: (Geospiza magnirostris) is less common and can be found only in the bigger Islands. All these finch species have similar appearance, color and behavior. It is a real challenge for birdwatchers to differentiate or guess the species to which each Galapagos ground finch belongs. More

(the medium ground finch Geospiza fortis and the Cactus finch G. scandens) have been studied for up to 12 years by Grant and his co-workers (Grant, 1986; Gibbs and Grant, 1987a-c). Darwin's finches are small passerine birds that are famous for their tremendous adaptive radiation on the Galapagos. They breed during the wet season. The ground finches live mostly on seeds, but also feed on pollen and nectar produced by the opuntias. More

Medium ground finches eat a range of food including about two dozen kinds of seeds. ... Write a short news story about the medium ground finches on the island of Daphne. Major. Tell your readers about how the drought of 1977 led to changes ... Adaptation and function of the bills of Darwin 's finches ... More

the medium ground finches of Galápagos is a prime example of how short term evolutionary adaptations can arise driven by environmental changes. We found this one foraging adjacently to another famous figure of the Galápagos Islands - and the world's loneliest bachelor - namely Lonesome George. Et av de virkelig store ikonene på Galápagos, mellomjordspurv (Geospiza fortis). More
