Birds of Quivira – Ruddy Turnstone

bill duncan, birds, Quivira National Wildlife Refuge, wildlife

With unique coloration and behavior, the Ruddy Turnstone is a shorebird that does not take a second guess to identify. The photograph above captures this conspicuous behavior for which these birds have earned their name. They do turn anything that they can – looking for any type of small invertebrate that may be hiding underneath. Anything includes dead fish or other animals, shells or trash washed up on a beach.

These guys typically migrate along the coasts and finding them in the interior is not that common. Although we missed out on finding any Buff-breasted Sandpipers during this visit, we were glad to have the opportunity to watch these guys in action.

From the Garden – Lacewings

macro, wildlife

The Lacewing (order Neuroptera, roughly translated to “nerve-wings”) insects are important predators of economic pests. Lacewing larvae are voracious predators that prey upon soft-bodied arthropods such as aphids, scale and whitefly. I have not yet been able to photograph one of these killer larvae yet, and that may be due to their tendency to cover themselves in pieces of trash (including parts of their victims) they find in their environment as camouflage. Another interesting bit of information about these insects is how their eggs are deposited. The photograph below shows the eggs deposited on long thread-like stalks, which have been hypothesized to be deterrents to not only predation, but cannibalism as the larvae hatch and immediately begin to look for something to eat.

Birds of Quivira – The Egrets

birds, Quivira National Wildlife Refuge, wildlife

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?

From the Garden – Redbud Bruchid

Backyard Gardens, macro, wildlife

The Redbud Bruchid (Gibbobruchis mimus), as its name suggests, is one of those perfect examples of insect-plant specialization. The larvae of this species will only grow on the seeds of Redbud trees and perhaps on those of a relative or two.

Being extremely small (2.5 – 3 mm), these cute guys are quite the challenge to photograph. Adults feed on plant tissues (flower petals, pollen, nectar, etc…) and I typically have seen them feeding on my Echinacea flowers.

The guy above can be seen creating or adding to a hole in a flower petal. I much prefer them to the exotic invasive Japanese Beetles that tend to leave nothing behind.

The Bruchids are a subfamily or “tribe” found within the quite large family – the Chrysomelidae, known as “Leaf Beetles”.

If you know the size of an individual blossom of the Common Milkweed (Asclepias syriaca), the image above will give you a good idea on just how small these little guys are.

Thanks for stopping by.

Birds of Quivira – Long-billed Dowitcher

birds, Quivira National Wildlife Refuge, wildlife

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.

From the Garden – Bumble Bee

Backyard Gardens, macro, wildlife

Even with a couple great guides, I still am having troubles identifying the Bumble Bees. Getting the right image makes a big difference and I need to remember to take photos from multiple angles in order to get sure IDs. Missouri is home to ten species of bumblebee and I imagine identification will get easier with practice.

The native wildflowers in my yard are huge attractants for all bees, and especially bumblebees. The long-tongued bumblebees and honeybees cover the Echinacea and Silphium in the garden, while the smaller, shorter tongued species are mostly attracted to the Rudbeckia.

Thanks for stopping by!

Birds of Quivira – The Waterfowl

birds, Quivira National Wildlife Refuge, wildlife

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.

Killdeer Nest

birds, Nesting Birds of Missouri, wildlife

Sarah and I found this girl on her eggs this spring at Clarence Cannon NWR. According to Harrison (Peterson Field Guides – Eastern Birds’ Nests), the male of the species will “make various scrapes in the ground” and one is chosen by the female to deposit and incubate her eggs. As most of us familiar with the bird know, the Killdeer will usually nest far from water and often within human disturbed habitat. This girl’s nest was along the side of a gravel road within the refuge.

From the Garden – Soldier Fly

This species of soldier fly (Ptecticus trivittatus) is attracted to rotting vegetation and can often be found around compost heaps. This guy was seriously into some cucumber scrap I threw into the yard.

Day Two in Southwestern Puerto Rico – Cabo Rojo National Wildlife Refuge

birds, Puerto Rico - 2015, wildlife

I found myself on the second day a little further from Ponce, where I visited what has been described as the most important habitat in the Caribbean for migratory and resident shorebirds – the Salt Flats of Cabo Rojo NWR.

The refuge was first established in 1974, when it was comprised of a patch of subtropical dry forest near the coast in the southwestern tip of the island. This patch of nearly 600 acres was gifted to the US Fish and Wildlife Services by the CIA, of course. Unfortunately, this initial plot of land and the nice looking visitor’s center that is run by the USFWS is closed on Sundays, the day of my visit. Within the tall wire fence, the forest and savanna habitat looked very inviting. Immediately upon exiting the car to deposit some used coffee I watched as a pair of striking Puerto Rican Woodpeckers flew directly over me to land in a tree, bathed in the light of the golden hour, just on the other side of the fence. Of course they would not stay put while I put the camera together.

Subtropical Dry Forest is characterized by low annual rainfall (~30-35″ annually), high temperatures of over 100 F and plants adapted to such climatic conditions. Within such habitat plants normally achieve heights of 15″ on average. Plants are further adapted to these hot, xeric conditions by having small, waxy leaves – often shaped into thorns to dissuade herbivores.

Several cactus where found throughout the refuge. The photo above captures not only cactus, but a dry-adapted lichen, known as tropical mistletoe, that was quite common as well.

In 1999, approximately 1300 acres of salt flats were added to the refuge. These salt flats are very important for overwintering shorebirds, but I was a bit late for this as the majority of these birds were already headed north to the arctic tundra. However, I was able to find a few straggling migrants as well as nesting species – including several endemics of Puerto Rico.

The Salt Flats are considered Important Bird Areas by Birdlife International and the Western Hemisphere Shorebird Reserve Network. This area serves as important nesting grounds for the Black-necked Stilt, Antillean Nighthawk, Least Tern and both Wilson’s and Snowy Plovers, among others.

This refuge is also important habitat for the federally endangered Yellow-shouldered Blackbird. This author considers himself fortunate to find one bird, but was crushed by not being able to get a photograph. 😦

One plant that I encountered over most of my travels on this corner of the island was very common within Cabo Rojo – Wild Cotton (Gossypium hirsutum). This wild relative of cultivated cotton is perennial in nature and adapted for salty, sandy soils.

There is quite a length of trails throughout the salt flats and the native islanders used these for recreation activities like running and bike riding as well as means to get to different beaches around this section of coast. Near the area where I parked was some very attractive mangrove groves that attracted the Yellow Warbler.

Four species of mangrove are commonly found on the island: Red, Black, White and Button. Tide lines and preference/tolerance of submerged roots is the primary reason behind how the different species are composed along Puerto Rico’s coastlines.

With only approximately 500 pairs known on the island, I was quite fortunate to find and photograph these White-cheeked Pintail.

Towards one end of the salt flats were some of the workings that produced the salt for non-food purposes. I could not determine if the works were still in production, or if it was left mainly for show.

I observed only the Black-necked Stilt utilizing this area, as the next two images suggest, they are quite tolerant of the saline conditions.

I never found a nest or chicks, but the way these guys were harassing me during this part of my hike, I would be surprised if there was not some sort of nesting activity going on nearby.

So, that was Cabo Rojo. I would love to visit during a weekday when the dry forest/savanna section is open and when the few narrow roads that wind through this narrow bottleneck are not clogged with vacationing islanders.

Next time, I will recap the last day of my visit where I ventured a bit north in latitude to visit the Tolkienesque mountain rainforest known as the Elfin Woods of Maricao State Forest.

Thanks for your visit.
