点评:Sonny Bono Salton Sea National Wildlife Refuge lived up to its reputation as a birding hotspot even though we had missed the large flocks of migrating waterfowl including the snow geese and Canada geese which had already departed. The birding began upon arrival while checking out the Visitors Center where we saw several Gambel’s quail running around. Along the path taking us to Rock Hill we saw Abert’s Towhee and Verdin. A Northern Harrier took a low pass over us. There were still many waterfowl in the ponds but those were off-limits to visitors and we had to make do with binoculars and zoom lenses. Given the distance heat shimmer degraded the quality of clarity of our view and the sharpness of the pictures taken.
The easiest to identify were the largest, of course, including Great Blue herons (one of which flew quite close to use) and the many American White Pelicans of which there were several feeding in the ponds. There were countless Northern Shovelers scattered throughout the different ponds. Pied-billed grebes, double-crested cormorants, American avocet and green-winged teal also shared the water. Black Phoebe, red-winged blackbirds, and Northern Rough-winged swallow were some of the non-waterfowl birds we spotted.
There were great views of Salton Sea from the top of Rock Hill.
Be sure to explore some the nearby fields. We couldn’t miss a large flock of cattle egrets in a field but quite close to road. Mixed in with them were white-faced ibis. They were a spectacular sight when they flew off. The star bird of the area was the Burrowing owl. We initially had a hard time spotting them. Once we knew what we looking for - small, upright blobs darker than the orange earth - along the embankments. They were tiny but pack fierce glares.
翻译:尽管我们错过了大群迁徙的水禽,包括已经离开的雪雁和加拿大雁,但桑尼博诺索尔顿海国家野生动物保护区仍不负其观鸟胜地的美誉。我们抵达后,在参观游客中心时,看到了几只山鹑四处奔跑,开始观鸟之旅。在通往罗克希尔的路上,我们看到了阿伯特鸫和绿苇莺。一只北鹞低空飞过我们头顶。池塘里仍有许多水禽,但游客不能看到它们,我们只能用双筒望远镜和变焦镜头。由于距离较远,热浪降低了视野的清晰度和拍摄照片的锐度。
最容易识别的当然是最大的,包括大蓝鹭(其中一只飞得很近,很难看到)和许多美洲白鹈鹕,其中有几只在池塘里觅食。无数的北方琵嘴鸭散布在不同的池塘里。斑嘴鸊鷉、双冠鸬鹚、反嘴鹬和绿翅鸭也共享这片水域。我们发现的一些非水禽包括黑鹂、红翅黑鹂和北粗翅燕。
从罗克希尔山顶可以看到索尔顿湖的壮丽景色。
一定要去探索附近的田野。我们不会错过田野里一大群牛背鹭,但离公路很近。白脸鹮和它们混在一起。它们飞走时景象十分壮观。该地区的明星鸟是穴鸮。我们最初很难发现它们。一旦我们知道我们在寻找什么——沿着堤岸,那些比橙色泥土颜色更深的小而直立的斑点。它们个头很小,但目光凶猛。
