Problem: While some birds are essentially territorial or live in small family groups, other birds may form large flocks. The principal benefits of flocking are safety in numbers and increased foraging efficiency. Defence against predators is particularly important in closed habitats like forests, where ambush predation is common and multiple eyes can provide a valuable early warning system. This has led to the development of many mixed-species feeding flocks, which are usually composed of small numbers of many species; these flocks provide safety in numbers but increase potential competition for resources. Costs of flocking include bullying of socially subordinate birds by more dominant birds and the reduction of feeding efficiency in certain cases.

Answer: safety in numbers and increased foraging efficiency

Problem: Britain now threatened to withdraw its subsidies if Prussia didn't consider offering concessions to secure peace. As the Prussian armies had dwindled to just 60,000 men and with Berlin itself under siege, Frederick's survival was severely threatened. Then on 5 January 1762 the Russian Empress Elizabeth died. Her Prussophile successor, Peter III, at once recalled Russian armies from Berlin (see: the Treaty of Saint Petersburg (1762)) and mediated Frederick's truce with Sweden. He also placed a corps of his own troops under Frederick's command This turn of events has become known as the Miracle of the House of Brandenburg. Frederick was then able to muster a larger army of 120,000 men and concentrate it against Austria. He drove them from much of Saxony, while his brother Henry won a victory in Silesia in the Battle of Freiberg (29 October 1762). At the same time, his Brunswick allies captured the key town of Gottingen and compounded this by taking Cassel.
How many troops did Frederick have left?
