This Great Egret is in full breeding plumage and has acquired the green mask that are indicative of adult birds. This one has also sustained an injury to its bill, perhaps from an aggressive encounter with another male?
What is more striking than a Snowy Egret?
Finally, I realized I haven’t included too much in terms of habitat shots of Quivira. Here is a pano of one of the more productive sections of the reserve. It’s a pity to think of how much of this habitat has been lost on this continent. How many care or even know?
Considered conspecifics for decades, both the Long-billed and Short-billed Dowitchers breed in the high arctic. Differences in plumage, migratory routes and breeding isolation, followed by allozyme and mtDNA evidence suggested separate species status. The Long-billed, pictured in this post was the only Dowitcher species Steve and I were find at Quivira. This is not altogether surprising due to the Long-billed’s preference for freshwater during migration and the Shirt-billed’s tendency to stick to marine environments.
The long, thick legs and bill give indication as to the depth of water in which these birds feed and they probe for prey using a rapid up and down motion that is quite reminiscent of the action of a sewing machine.
Most of the waterfowl had long since migrated north by the time Steve and I visited Quivira in May, but we were able to find a few. We encountered a few Eared Grebe and with the winds as high as they were, the waves were impressive in such shallow bodies of water.
Blue-winged Teal were the most abundant of the waterfowl.
Finally, we watched this gorgeous pair of Canada Geese in golden hour light. They seemed more appropriate here than in any other setting I had ever seen them before.
The sparrows were not to be outdone by other groups of birds. Steve and I were fortunate to find a number of interesting sparrows. Unfortunately most were difficult and uncooperative, at least when light was good. The Lark Sparrows, although gorgeous, were giving us a little confusion with their unfamiliar song.
While moving through the woodlots of Quivira, we found a couple of sneaky, tricksy Lincoln’s Sparrows.
My first time hearing the song of Clay-colored Sparrow. Their insect-like trills were somehow quite appealing and I looked forward to hearing them in the mornings.
The Harris’s Sparrow is another classic western sparrow found at Quivira.
Finally, the Savannah Sparrow, which can be found in different forms across the continent.
A medium sized, markedly-colored Calidris sandpiper, the Sanderling is one of the most highly traveled migrant birds on the planet. Breeding only in the far north arctic, some Sanderlings will winter as far south as Cape Horn of South America. Individuals in breeding plumage are easily identified with close enough inspection by looking for the rusty-gravel coloration. Winter and juvenile forms are contrasty black and white. All birds lack a back toe, which are typically found on shorebirds.
Much like the Meadowlarks, Steve and I observed an abundance of both Eastern and Western Kingbirds. We were surprised by the close proximity of the assumed territories. The typical super-aggression shown by the Eastern Kingbirds did not seem to be delivered to either the Westerns or conspecifics.
The Piping Plover, or as Pete Dunne has named them – the Sand Wraith, was one of the more special birds that Steve and I were able to view and photograph at Quivira this spring. The Piping can be identified by its top color of dry sand (vs. the wet sand-colored top of the Semipalmated Plover) and its bright yellow-orange legs (vs. the gray-legged Snowy Plover).
There are currently an estimate of ~2500 pairs of Piping Plover left on the planet – causing this species to be listed on the endangered species list. Unlike most of the shorebirds – who pass over most of North America on their migration north to nest in the arctic tundra, the Piping Plover dares to nest on Atlantic coasts and sandy shores of lakes of the northern plains. It is here where its nesting needs have been overlooked by the desires of man who has converted its coastal habitat to development and flooded its fresh-water beaches and whose dogs and cats have made easy meals of its eggs and chicks.
Cousin to the slightly smaller Piping Plover and the ubiquitous, double-striped Killdeer, the handsome species that is the subject of this post is the Semipalmated Plover. Semipalmated refers to this bird’s semi-webbed toes.
I find it interesting that these birds are typically tolerant of feeding among other shorebird species such as Piping plovers and Peep Sandpipers, but will not tolerate conspecifics during migration, aggressively defending a feeding territory.
I have read it described that the Semipalmated Plover is the color of wet sand, while its similar looking cousin, the Piping Plover, is the color of dry sand. Stay tuned next time we visit Quivira NWR when I plan on showcasing this species.
Located in south-central Kansas, Quivira NWR lies within the overlap of the ranges of both Eastern and Western Meadowlarks. We had observed both species (mostly Eastern) in a past trip or two to western Missouri, but Steve and I were immersed in an almost 50/50 mix of the two at Quivira. According to the literature, these guys participate similarly in their respective habitats, although Westerns prefer things a bit drier. Visually, the two species are quite similar and depending on the season may be difficult for even the most experienced birder to be certain of their ID based on solely visual cues. I believe the two images presented here do represent some of these subtle visual differences. The Western appears to be less contrasty and lighter in color overall than the Eastern. Pay close attention to the sub-moustachial area in the two birds pictured. In the western, the yellow from the chin spills over into this area, but remains a clear and distinct white in the Eastern. Lastly, the head stripes of the Eastern are darker than those of the Western.
Advertisement songs and calls are quite distinct between the two species and should always be sought for best identifications. I was quite confident in this knowledge and sure that I had this down until I read recently, that because these are songbirds after-all, and songbirds learn their songs, there may be some similarities – especially where the two ranges overlap. So, maybe the calls are the only true tool we have?
The demure, upturned bill, the black and white striped pattern and the gorgeous warmly colored head and neck make the American Avocet in breeding plumage unmistakable.
The Avocet is adapted at finding its bread in a variety of scenarios. It can fish by probing the shallows with its needle-like bill tip, but it is equally comfortable at being in over its head and using its bill as a scythe to collect its prey, sometimes while literally swimming.
I have seen no more than four of these guys at a time in winter plumage in Missouri. During four days at Quivira Steve and I observed dozens.
In the above image you can see the large strides in deeper water this bird’s blue, stilt-like legs afford it.
