Birds are too, particularly albatrosses which get caught as the long line is being deployed over the stern of a fishing boat steaming slowly forward. As each baited hook slides over the stern it is accessible in the ship's wake for a few seconds before a weight attached to its monofilament line pulls it under. Albatrosses follow long liners and grab the baits before they sink, getting caught by the hook in the process. There is a weight at the end of each down line, and when the albatross can no longer resist its downward pull it drowns. Because stopping the ship to disentangle an albatross would take too long and might tangle the longline, fishermen simply continue on their way, leaving dying albatrosses struggling in their wake.
Albatrosses are species that reproduce very slowly.
In the case of the wandering albatross, the largest of all flying birds, courtship takes two years before mating ever occurs followed by the laying of the first egg. A Wandering albatross has a wingspread of twelve feet, with the wingspreads of some individuals reported at up to fourteen feet. I am one of a relatively small minority of humans who have seen them though. In fact I have spent thousands of hours of my life watching albatrosses soar. Nothing I have seen in Nature is more beautiful.
