About These Birds
白头海雕
The bald eagle is the national bird and symbol of the United States. Once endangered due to DDT pesticide use, it made a remarkable recovery and was removed from the endangered species list in 2007. These powerful raptors build the largest tree nests of any bird, some weighing over two tons.
Great Tit
The great tit is the largest European tit and one of the most studied wild birds in the world. Research at Wytham Woods in Oxford has monitored great tit populations since the 1940s, contributing enormously to ecology and evolution. These innovative birds famously learned to open milk bottle tops in 20th-century Britain.
