Java Message Service
Our look is the result of reader comments, our own experimentation, and feedback from
distribution channels. Distinctive covers complement our distinctive approach to technical
topics, breathing personality and life into potentially dry subjects.
The image on the cover of Java Message Service is a passenger pigeon (Ectopistes
migratorius), an extinct species. Although these birds had some personality quirks that
might have doomed their existence anyway, it was humans who proved their ultimate
undoing.
In the mid-1800s, passenger pigeons were the most numerous birds in North America.
Several flocks, each numbering two billion or more birds, lived in various habitats east of
the Rocky Mountains. Flocks migrated en masse in search of food, without regard to
season, and a good food source might keep a flock in one place for years at a time. (In fact,
John James Audubon observed that nearly the entire passenger pigeon population once
stayed in Kentucky for several years and were seen nowhere else during this time.)
Whole flocks roosted together in small areas, and the weight of so many birds - often up to
90 nests in a single tree - resulted in destruction of forests, as tree limbs and even entire
trees toppled. (The accumulated inches of bird dung on the ground probably didn't help,
either.) These roosting habits, combined with high infant mortality and the fact that female
passenger pigeons laid a single egg in a flimsy nest, didn't bode well for the long-term
survival of the species.
It was the harvesting of passenger pigeons for food, however, that drove them to
extinction. In 1855, a single operation was processing 18,000 birds per day! Although even
Audubon himself thought that the prodigious pace of passenger pigeon processing
wouldn't have an adverse effect on the birds' population, he was wrong, because the last
passenger pigeon died in the Cincinnati Zoo in 1914.
