Clubbing is an enlargement of the ends of the fingers and a downward sloping of the nails. Although it's not caused by chronic obstructive pulmonary disease (COPD), it can be a sign of coexisting lung cancer or other lung disorders in patients with COPD. Clubbing is sometimes called digital clubbing. It can affect the fingers and/or toes.
Relatives. Darwin's finches can be divided into groups based on beak type. There are three species of tree finch: the small tree finch, medium tree finch, and large tree finch. Tree finches have grasping beaks.
In addition to Darwinâs finches, there are giant tortoises and spectacular songbirds such as the vermillion flycatcher. The plants are just as interesting. In the highlands, you can see trees that evolved from daisies and are covered in colorful mosses and lichens, while in the lowlands there are many cacti.
