Sometimes circumstances such as a good breeding season followed by a food source failure the following year lead to irruptions in which large numbers of a species move far beyond the normal range. Bohemian waxwings Bombycilla garrulus well show this unpredictable variation in annual numbers, with five major arrivals in Britain during the nineteenth century, but 18 between the years 1937 and 2000. Red crossbills Loxia curvirostra too are irruptive, with widespread invasions across England noted in 1251, 1593, 1757, and 1791.
For what reason would birds mor far beyond the normal range?
a good breeding season followed by a food source failure

Paleoptera and Neoptera are the winged orders of insects differentiated by the presence of hardened body parts called sclerites, and in the Neoptera, muscles that allow their wings to fold flatly over the abdomen. Neoptera can further be divided into incomplete metamorphosis-based (Polyneoptera and Paraneoptera) and complete metamorphosis-based groups. It has proved difficult to clarify the relationships between the orders in Polyneoptera because of constant new findings calling for revision of the taxa. For example, the Paraneoptera have turned out to be more closely related to the Endopterygota than to the rest of the Exopterygota. The recent molecular finding that the traditional louse orders Mallophaga and Anoplura are derived from within Psocoptera has led to the new taxon Psocodea. Phasmatodea and Embiidina have been suggested to form the Eukinolabia. Mantodea, Blattodea, and Isoptera are thought to form a monophyletic group termed Dictyoptera.

Around 930 BCE, the kingdom split into a southern Kingdom of Judah and a northern Kingdom of Israel. From the middle of the 8th century BCE Israel came into increasing conflict with the expanding neo-Assyrian empire. Under Tiglath-Pileser III it first split Israel's territory into several smaller units and then destroyed its capital, Samaria (722 BCE). An Israelite revolt (724–722 BCE) was crushed after the siege and capture of Samaria by the Assyrian king Sargon II. Sargon's son, Sennacherib, tried and failed to conquer Judah. Assyrian records say he leveled 46 walled cities and besieged Jerusalem, leaving after receiving extensive tribute.
