Sometimes you’re the predator, sometimes you’re the prey…
I walked around a small reconstructed cabin at Fort Ridgley state park wanting to peer in the windows at the back and see what the interior looked like.
In the process I almost stepped on a leopard frog sitting in the grass near the sidewalk. The frog jumped to the base of the cabin, scaring a grasshopper (that I presume had been sitting on the sidewalk) to jump higher on the wall to avoid the frog.
But then I noticed a “pack” of garter snakes creeping toward the corner of the cabin near the frog.
Local Minnesota photographer Paul Sundberg captured just such an event on a recent canoe trip in the Boundary Waters when he spied a garter snake engulfing an American Toad. Once consumed, the toad made quite a large bulge in the snake’s body.
Sometimes you’re the predator — sometimes you’re the meal! And so on up the food chain.
Meadow Blazing Star attracts butterflies like catnip attracts cats. They stay on the plants for hours, flying around the flowers, dipping into them, chasing each other, and just generally hanging out by the vibrant purple blooms. I highly recommend it for your garden.
These Monarchs are most likely the final generation of the summer — the individuals that will fatten up on rich nectar resources from blazing star and other flowers and then begin a 2-3,000 mile journey to their overwintering sites in montane forest areas of central Mexico. Flying about 50-100 miles a day, it will take them more than two months to complete their migration. They depend on finding more nectar resources as they travel south through the American midwest, then south to Texas, and on through northern Mexico — an amazing feat of stamina and navigation in order to return to their overwintering site.
The Chiracahua mountains of southeastern Arizona offer a multitude of scenic vistas, as well as a bounty of incredible wildlife to see.
The Chiricahua Mountains rise more than 6,000 feet above the desert floor that surrounds them, making them “islands in a sea of desert”. A variety of life zones occur along a gradient from hot, dry desert to cool pine forest at peak elevation, which means these montane islands are a hot spot of biodiversity.
Five rivers feed into the 200,000+ acres of wetlands that make up the second largest river delta system in the U.S. just north of Mobile Bay in southern Alabama. The Mobile-Tensaw delta’s expanse of swamp, bog, natural rice paddies, canals, and rivers makes this area of Alabama a real biodiversity hotspot where you can find more species of fish, turtles, snails, crayfish, and oak trees than anywhere else in North America. Harvard ecologist E.O. Wilson has called it North America’s Amazon, and so it was a real treat to venture out on a small boat to explore some of the smaller waterways of the delta for ourselves.
The southeastern U.S., and the Mobile delta in particular, was a refuge for species driven south during the ice ages of the Pleistocene glaciation. Warm temperatures year-round and plenty of rainfall (averaging 70 inches per year) ensure the most equitable conditions for life to survive, and so it has in this cradle of biodiversity.
A little Spotted Sandpiper had the entire beach of Vadnais reservoir to itself and moved slowly along the shoreline probing now and then in the mud and under leaves as I stood quietly and watched.
Spotted Sandpipers are likely the most widespread breeding sandpiper in North America, nesting from northern most Alaska to the mid-continental U.S. along rivers, lakes, and streams.
And their breeding system is particularly interesting because they exhibit a sex role reversal compared to most other bird species. Instead of the typical female role of incubation and hatchling care, Spotted Sandpiper females “collect” multiple males, laying a clutch of eggs in each male’s nest, which he will then incubate. After they hatch, the male is in charge of protecting and providing food for the chicks, while the female goes off to find another male to mate with.
Female Spotted Sandpipers arrive first on the breeding ground, establish their territory, and then compete with each other for males to mate with. Since females can store sperm from multiple matings for up to a month, the male may be incubating and tending to chicks that are not his offspring! This breeding strategy, called polyandry, is rare among birds but is found in several shorebird species, in Northern Jacanas, occasionally in Acorn Woodpeckers, and in Harris Hawks.
Prairie parkland landscapes are at their peak golden color now. The fall landscape is transforming daily, and with the nice fall weather lately, it’s a glorious time to be out walking around. I’ve given up trying to find the migrating birds at this points and am just enjoying the golden colors everywhere.
We spent a beautiful morning walking along the St. Croix river at Afton State Park recently, and I noticed that it seems more like fall weather now, and a lot less like summer. What a difference a couple of weeks makes in the climate here.
There are lots of trails to explore in the Lake Tahoe basin, and we took the grandkids on a “walk” from their cabin on Fallen Leaf lake all the way to a swimming beach on Lake Tahoe — an almost 7 mile hike. Naturally, there were a number of stops to rest and swim at places along the way, and there was a promise of ice cream at the end of the hike, and that’s all it took to get the kids there.
