The hummingbird is also the only bird species able to fly backwards, which proves a helpful power when feasting on the nectar of plants and insects. This allows them to survive the many hours of the night without food." She told Newsweek: "They have extremely high metabolisms and burn lots of calories during the day, but at night they can slow down their metabolism and go into a very deep sleep. Emma Greig, project leader of Project FeederWatch at Cornell Lab of Ornithology, said one reason hummingbirds are so exceptional is because they are the smallest birds in the world. These minuscule birds are a wonder of the natural world, packing several almost otherworldly powers into their barely believable bodies.ĭr. The Joshua Humphreys Papers, including financial records, hand-drawn diagrams, correspondence and other family documents, are available for research use at the Historical Society of Pennsylvania.Hummingbirds have hypnotized humans since our ancestors first reached the Americas centuries ago.

Two ships, USS Humphreys (DD-236) and USNS Joshua Humphreys (T-AO-188), were named for Humphreys.īuilding 197 of the Washington Navy Yard was completely renovated in 2014 and renamed in honor of Humphreys. His grandson, General Andrew Atkinson Humphreys, served throughout the American Civil War. His son was another noted naval architect, Samuel Humphreys. His uncle was Charles Humphreys, a member of the Continental Congress. In 1789, Humphreys was elected to the American Philosophical Society. These vessels were larger than other ships of their class and formed the core of the Navy during the War of 1812, and scored several victories against British ships, although two were captured. The USS United States was built by Humphreys in Philadelphia, and was the first of the new ships to be launched on May 10, 1797. The ships Humphrey built were more stable than other ships at the time and could carry as many guns on one deck as others did on two decks. His designs called for ships that were longer and wider than usual, sat lower in the water and were able to equal the speed of any other fighting ships. Reputedly, one of the inspirations for his frigate designs was the South Carolina. He was appointed naval constructor on June 28, 1794, and began work on these ships, the beginnings of the U.S. When Congress passed the Naval Act of 1794 providing for the construction of six frigates, it called on him to design them. His main shipyard complex was on the Delaware River in the Southwark neighborhood. In postwar Philadelphia, Humphreys became a shipbuilder in Philadelphia and was one of the most sought after and busiest. During the American Revolutionary War he was active as a designer, and played a major part in planning the 32-gun frigate USS Randolph before the British Army occupation of Philadelphia halted that effort. During his apprenticeship, his instructor died and he was placed in charge of the establishment. As a youth, Humphreys was apprenticed to a shipbuilder in Philadelphia, Pennsylvania.
