Our trip this afternoon confirmed that at least that last component of larid behavior persists.<\/p>\n<p>Strong&#8217;s work in Green Bay ranked him among\u00a0<em>the\u00a0<\/em>authorities of his day on gull behavior. In 1917, a few months after the entry of the United States into the war, he <a href=\"https:\/\/sora.unm.edu\/sites\/default\/files\/journals\/auk\/v040n04\/p0609-p0621.pdf\">turned his expertise to the investigation of another, more immediately practical problem<\/a>:<\/p>\n<blockquote><p>I read in &#8216;Science&#8217; the recommendation of the Committee on Zoology of the National Research Council that the problem of &#8220;utilization of gulls and other aquatic seabirds in locating submarines be studied.&#8221;<\/p><\/blockquote>\n<p>Strong&#8217;s experience had taught him that it would useless to try to train gulls captured as adults, so he secured a small corps of chicks of flighted juveniles to work with. His preliminary results were encouraging: the young birds quickly grew tolerant of their human keepers, and\u00a0<strong>herring gulls<\/strong>, he found, could recognize new situations in their environment &#8212; the hope was, of course, that they could be taught to recognize submarines and somehow &#8220;alert&#8221; their human monitors to the threatening presence.<\/p>\n<p>Strong&#8217;s scheme proposed capturing large numbers of unfledged gulls, raising them, and keeping them on board navy ships until &#8220;regions of danger&#8221; had been reached. Once released, he predicted, the gulls would make short feeding flights from their &#8220;home&#8221; ship, when<\/p>\n<blockquote><p>by careful watching &#8230; variations in their movements would at least suggest that an unusual object was in the water.<\/p><\/blockquote>\n<p>The plan &#8212; of which Strong admitted &#8220;that the chances of success were limited, to say the least&#8221; &#8212; was never carried out. While Strong and his colleagues were working out the details, other, &#8220;very efficient methods for detection of submarines were developed,&#8221; and the &#8220;raid&#8221; on the gulls&#8217; nesting colonies was never carried out.<\/p>\n<p><a title=\"Herring gulls, Door County, Wisconsin by Rick Wright, on Flickr\" href=\"https:\/\/www.flickr.com\/photos\/rickwright\/14486503326\"><img decoding=\"async\" loading=\"lazy\" src=\"https:\/\/farm4.staticflickr.com\/3856\/14486503326_6b06be5a7f_z.jpg\" alt=\"Herring gulls, Door County, Wisconsin\" width=\"640\" height=\"403\" \/><\/a><\/p>\n<p>The\u00a0<strong>herring gulls\u00a0<\/strong>of Lake Michigan could go back to their loafing and squabbling, activities they continue to excel in today.<\/p>\n<p><em>Strong never tells us what else he saw out in the gulleries of Wisconsin and Michigan.
