Common Flicker

<em>Colaptes auratus</em> is a large woodpecker in the family Picidae, order Piciformes, commonly known as the northern flicker. Unlike most woodpeckers, this species frequently forages on the ground, using its long tongue to extract ants and beetle larvae from the soil. <em>Colaptes auratus</em> is documented in Europe and the United States, where it inhabits open woodlands, forest edges, suburban areas, and parks with mature trees suitable for nesting. The species is notably adaptable in its habitat use and is one of the most widespread woodpeckers in North America. It is easily recognized by its brownish-barred plumage, spotted underparts, and a bold white rump patch visible in flight. Two main subspecies groups are recognized — the yellow-shafted form in the east and the red-shafted form in the west — which interbreed extensively where their ranges meet. Flickers are cavity nesters, excavating holes in dead or dying trees. Biological traits of this species remain poorly documented in the scientific literature.

Common Seahorse

The common seahorse is found in tropical and temperate waters. Males carry and deliver the babies.
