I was going to pass by the Nabesna Road again in about a month, and I had the perfect setup waiting for me. \u00a0If (and it&#8217;s always a big if with nesting birds) the pair of waxwings didn&#8217;t abandon the nest, and nothing predated the young, I&#8217;d have a &#8220;captive audience&#8221; on my return trip to see what else waxwings can say.<\/p>\n<p>From that first observation of the pair I noticed several things. \u00a0First, the birds had both very short (only a few notes) and more normal long versions of their trills, and they seemed to serve different functions. \u00a0The long trills, what I consider the classic Bohemian Waxwing call, were typically given at long intervals and most often when a bird took off from an exposed perch. \u00a0The short trills, on the other hand, were given much more frequently, often by a bird perched prominently on a spruce tree, both when the other member of the pair was present and when it had flown off. \u00a0Playback of the long call either elicited no response, or the bird flew away, whereas the short call would bring the bird in close, and at times even low. \u00a0My suspicion is that the short call serves some kind of territorial purpose, but even after watching the birds for a long while I am not entirely sure. \u00a0Examples of both the long calls and short calls are here:<\/p>\n<table>\n<tbody>\n<tr>\n<td><div class=\"iframe-wrapper\">\n  <iframe src=\"http:\/\/www.xeno-canto.org\/embed.php?XC=192134&#038;simple=0\" frameborder=\"0\" style=\"height:220px;width:400px;\">Please upgrade your browser<\/iframe>\n<\/div><\/td>\n<td><div class=\"iframe-wrapper\">\n  <iframe src=\"http:\/\/www.xeno-canto.org\/embed.php?XC=192133&#038;simple=0\" frameborder=\"0\" style=\"height:220px;width:400px;\">Please upgrade your browser<\/iframe>\n<\/div><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Fast forward a month, and I was back on the Nabesna Road. \u00a0I was ecstatic to find that the nest was still there, and four well-feathered young were looking healthy and alert in it! \u00a0Before I even got into position to record the nest I got a good recording of another, completely different vocalization &#8211; a very high-pitched, clear, descending whistle, very much like the &#8220;seer&#8221; call of a thrush. \u00a0This was clearly an alarm call, given at my presence, though the birds quickly calmed down and resumed their normal behavior. \u00a0I was beginning to wonder if that&#8217;s all the waxwings would do in alarm when a passing band of Gray Jays decided to drop in. \u00a0Boy did the waxwings take offense at that! \u00a0One of the birds outdid itself in driving off the offending jays, giving two more alarm calls while at it. \u00a0The first, given only twice an apparently in extreme alarm, was a harsh, low-pitched growl. \u00a0This was quickly followed by short trills that, while higher-pitched than the growl call, were significantly lower-pitched than their normal trills. \u00a0Some loud bill snapping was also thrown into the mix, making for quite the varied repertoire of alarm sounds! \u00a0You can hear both the clear whistle call and the other alarm sounds below:<\/p>\n<table>\n<tbody>\n<tr>\n<td><div class=\"iframe-wrapper\">\n  <iframe src=\"http:\/\/www.xeno-canto.org\/embed.php?XC=187767&#038;simple=0\" frameborder=\"0\" style=\"height:220px;width:400px;\">Please upgrade your browser<\/iframe>\n<\/div><\/td>\n<td><div class=\"iframe-wrapper\">\n  <iframe src=\"http:\/\/www.xeno-canto.org\/embed.php?XC=187758&#038;simple=0\" frameborder=\"0\" style=\"height:220px;width:400px;\">Please upgrade your browser<\/iframe>\n<\/div><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Once everything had returned to normal I took the opportunity to record the young begging. \u00a0Compared to the alarm calls the adults gave these calls were rather boring, essentially just a noisy version of the adult trills. \u00a0That recording is linked below:<\/p>\n<div class=\"iframe-wrapper\">\n  <iframe src=\"http:\/\/www.xeno-canto.org\/embed.php?XC=187688&#038;simple=0\" frameborder=\"0\" style=\"height:220px;width:400px;\">Please upgrade your browser<\/iframe>\n<\/div>\n<p>The time I spent with Bohemian Waxwings this past summer was near the top of my list of highlights for my trip to Alaska. \u00a0But even with everything I recorded from them, I think there is still more to be captured. \u00a0A few winters ago my friend Ian Davies heard what may actually be a stereotyped song from the species (something that has never been described or recorded) that:<\/p>\n<blockquote><p>&#8220;sounded almost like the pattern of a White-winged Crossbill song but with the calls of a Bohemian Waxwing&#8230;a longer sustained note of the standard musical rolling note,\u00a0on one pitch,\u00a0for maybe 1-1.5s,\u00a0and then changing without stopping to another pitch,\u00a0all of this with the standard clipped musical quality&#8221;<\/p><\/blockquote>\n<p>So there&#8217;s clearly more to discover about waxwings &#8211; a chance for anyone with a mic, or even an iPhone, to document something new if they&#8217;re in the right place at the right time!<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Waxwings have some of the simplest repertoires of all passerines, with no true &#8220;song&#8221;, or at least none that has been documented.
