Cardinalidae (sometimes referred to as the "cardinal-grosbeaks" or simply the "cardinals") is a family of New World-endemic passerine birds that consists of cardinals, grosbeaks, and buntings. It also includes several other genera such as the tanager-like Piranga and the warbler-like Granatellus .
The young leave the nest by 9–12 days of age and fly capably by the time they are a few weeks old. If the nesting attempt is disturbed, scarlet tanagers apparently are unable to attempt a second brood, as several other passerines can. In a study of 16 nests in Michigan, 50% were successful in producing one or more fledglings. [16]
Cardinals do not usually use their nests more than once. The female builds a cup nest in a well-concealed spot in dense shrub or a low tree 1–3 m (3.3–9.8 ft) off the ground. [30] The oldest wild cardinal banded by researchers lived at least 15 years and 9 months, although 28.5 years was achieved by a captive bird. [31]

Animal navigation is the ability of many animals to find their way accurately without maps or instruments. Birds such as the Arctic tern , insects such as the monarch butterfly and fish such as the salmon regularly migrate thousands of miles to and from their breeding grounds, [ 1 ] and many other species navigate effectively over shorter ...
In 1876 Augustus Hamilton found only six nests remaining, and because "certain miscreants destroyed a quantity of nearly-hatched eggs", tearing down saplings to procure them, the birds had abandoned the colony; Hamilton hoped the birds would "find a more secure place for their new home". [7]
Indigo bunting nest and egg laying. These birds are generally monogamous but not always faithful to their partner. In the western part of their range, they often hybridize with the lazuli bunting. Nesting sites are located in dense shrub or a low tree, generally 0.3–1 m (0.98–3.28 ft) above the ground, but rarely up to 9 m (30 ft). [22]
