Fun Facts about Pigeons

Pigeons are the most misunderstood of all creatures. Upon seeing a flock of pigeons, many people want     1     more than to run a mile in the other direction. Pigeons are commonly viewed as carriers and spreaders of disease, but that’s actually not true. People may be surprised to learn that these creatures have a number of     2     (fascinate) characteristics that should not be overlooked.

First, pigeons are highly skilled navigators (领航员). A pigeon can find its way back to its nest after     3     (transport) more than a thousand miles away from it! Because of this ability, humans     4     (use) pigeons to their advantage for centuries.

Another interesting yet not so admirable quality of pigeons is that they appear to be master procrastinators (拖延者). Scientific studies have shown that pigeons often delay the completion of a dull or troublesome task when an immediately     5     (convenient) alternative is available. Maybe pigeons could “give humans a run for their money” when it comes to putting off work!

Next, we come to the unpleasant topic of pigeon droppings. Urban dwellers are used to seeing streets     6     (litter) with these droppings. Although pigeon poo is seen as a problem in modern times, several centuries ago, it was actually considered a valuable commodity     7     its usefulness as a fertilizer.

Finally, it cannot be denied     8     intelligent creatures pigeons are. In addition to their navigation skills and excellent sense of hearing, they can distinguish between the letters of the Roman alphabet and differentiate between human faces in photographs.

So,     9     you feel disgusted upon encountering a pigeon,     10     (remember) that besides carrying little disease risk, these birds are smart creatures with many wonderful abilities.
