点评:We visited the Desert NWR on our drive from Las Vegas to Death Valley NP. Advertised as the largest NWR in the Lower 48 and famed for its population of bighorn sheep our visit was limited to the visitors’ center at Corn Creek. We had no expectation of seeing bighorn sheep so far down in the valley; we understood that to even have a chance of seeing them we would have to drive up to the eponymous Sheep Mountains. Limits of time and temperature (>100F) did not allow for that adventure.
We were looking for another fix of green vegetation amid the south Nevada desert and to hopefully find some avifauna, birding having now become an integral part of our visits to the natural world.
We did spot many birds but not too many species. These included Black-chinned hummingbird, Black-throated sparrow, Lucy’s warbler, Lesser goldfinch , Verdin, Violet-green swallow, Mourning dove, Indigo bunting, Ash-throated flycatcher, and Blue grosbeak.
We enjoyed the view of the Sheep Mountain range immediately to our north. To our south, across the valley, were the mountains of the Spring Mountains.
The spring-fed was a pleasure to walk through but we did enter the shady areas with much relief; even fairly early in the morning the July sun made for hot temps. Surrounded as we were by the Mojave desert it was quite the contrast to see flowing streams and relatively lush, green vegetation.
The only non-avian fauna we spotted was the Desert spiny lizard, on the side of the path, on fencing and up on in the trees. We could not spot the highly-endangered Pahrump poolfish in their tank.
翻译:我们从拉斯维加斯驱车前往死亡谷国家公园,途中参观了沙漠国家野生动物保护区。这里号称是美国本土48州最大的国家野生动物保护区,以其丰富的大角羊资源而闻名,但我们的行程仅限于位于玉米溪的游客中心。我们原本没指望能在山谷深处看到大角羊;我们知道,要想有机会看到它们,就必须驱车前往同名的绵羊山。时间有限,气温(超过100华氏度)也不允许我们进行这次探险。
我们想在内华达州南部的沙漠中寻找另一片绿色植被,希望能发现一些鸟类,观鸟已经成为我们自然之旅中不可或缺的一部分。
我们确实看到了不少鸟类,但种类不多。这些鸟类包括黑颏蜂鸟、黑喉麻雀、露西莺、小金翅雀、绿叶绿雀、紫绿燕子、哀鸽、靛蓝彩旗、灰喉霸鹟和蓝蜡嘴雀。
我们欣赏着北面绵羊山脉的景色。南面,穿过山谷,是春山山脉。
漫步在泉水滋养的溪流中是一种享受,但进入阴凉处后,我们感到轻松了许多;即使是清晨,七月的阳光也让人感到炎热。我们被莫哈韦沙漠环绕,看到潺潺的溪流和相对茂盛的绿色植被,感觉非常不一样。
我们发现的唯一非鸟类动物是沙漠棘蜥,它们栖息在路边、栅栏上和树上。我们没能发现鱼缸里濒临灭绝的帕朗池鱼。
