Etymology: Birdflight is a plain compound: "bird" plus "flight," with no special history behind the pairing. "Flight" comes from Old English "flyht," a noun formed from the verb "fleogan" (to fly), and the word has meant both the act of flying and the flock or swarm of birds moving together since before the year 1000. Combining it with "bird" yields the literal sense the noun now carries, a fairly transparent coinage whose parts explain it fully. The noun is recorded in English from around the 19th century, when writers describing natural history needed a compact way to refer to the way birds move through the air. Its sense is almost identical to the component words, so there is little semantic shift to trace. Its significance lies mainly in how easily English combines its everyday vocabulary into precise descriptive terms.
