This massive residential development sits on land in Etobicoke fronting on Lakeshore drive. The land was originally developed in the 20's and 30's with a string of motels which serviced tourists visiting Toronto and the area became known as the Lakeshore motel strip.
They prospered initially reaching their zenith in the 1950's but by the 1970's tourist trade had all but disappeared and the motels had become seedy and ill maintained, home to prostitutes, strippers, and the desperate. They struggled on into 2012 when the last of them fell to the wreckers ball. Redevelopment was initially slowed by turmoil in the financial markets but in recent years has progressed rapidly and continues even into today.

This is just because every Flickr feed needs a photo of a crocodile or alligator — *not* the footwear my son insists on wearing with socks, by the way. He tells me Crocs with socks is a thing. No offense if that’s your style where you live! 😉
I didn’t have a recent crocodile photo, so here’s Alfred the alligator. If I were his mummy crocodile, I’d definitely have named him Alfred. He’s got a bit of a thing for swimming in the rain, clearly. I swear I heard him singing:
I'm swimmin' in the rain,
Just swimmin' in the rain,
What a glorious feeling,
And I'm hungry again.
I'm laughing at clouds,
So dark, up above,
I could swallow that photographer whole,
If someone would just give him a shove.
No fun facts tonight because there is sooo much about these fantastic creatures I'd lose you! Suffice to say both crocodiles and alligators are fascinating survivors from the dinosaur era. After millions of years of evolution, they’ve become ferocious, expert hunters, inspiring equal parts respect and fear. We only have 1-2 fatalities a year from "salties" (saltwater crocodiles) over here. Maybe it's their revenge on people wearing that ridiculous footwear!
Happy weekend, everyone! :)

It’s not hard for the snail kite to plan its daily menu. The endangered raptor eats only one food: apple snails, and a lot of them—10,000 a year per bird. Catching the freshwater snails is a laborsome venture that involves waiting until the snail comes to the surface to breathe and—at the exact right moment—swooping down to grab it. Employing its perfectly adapted curved beak, the kite then extracts its escargot and repeats the process 27 more times, every day.
This specialist bird has been hit hard by habitat declines and other changes in the Florida wetlands it calls home. From 2000 to 2007, scientists noticed a steep decline in the number of snail kites, owing in part to two major droughts that left their wetlands parched. The decline was also affected by the rarity of the apple snail, which lives in a very particular habitat and has a relatively short lifespan. Without its snails, the snail kite's chances of survival were looking poor—until an unlikely invader found its way to Florida.
It turns out there is more than one variety of apple snail. The non-native South American apple snail likely made its way to the Sunshine State via the pet trade, possibly when a rash aquarium owner released the species into the wild. The South American snail, which can grow to nearly the size of a tennis ball, quickly outpaced its native cousin, which is only the size of a ping-pong ball. It lays more eggs, lives longer, and can adapt to more diverse habitats than the native variety, and so spread widely all over the Florida wetlands.
You may sense where this story is going. A recent study in Nature Ecology & Evolution found that the snail kite has rapidly evolved so as to be able to forage on this new, larger prey. The bills of the raptor, says Robert Fletcher, coauthor of the study and associate professor in the department of wildlife ecology and conservation at the University of Florida, have increased in size since the invasion of the South American snail.
“Bill size and shape are heritable, meaning that birds with larger bills pass the trait onto their offspring, and larger-billed birds have a higher survival rate,” says Fletcher. Parent kites that are able to handle the larger apple snail bring it back to their young, who are more likely to grow stronger, survive, and breed in turn. The first couple months of life are the most dangerous for young snail kites, who are just learning how to forage on their own and aren’t yet skilled at it. “Bigger-bill snail kites seem to survive much better during this time,” says Fletcher. The result: Numbers of large-bill snail kites have tripled in the past decade.

The apparent evolutionary success of Grevillea (Proteaceae family) might have been triggered by the highly efficient use of key nutrients. Research suggests that Grevillea plants have a selective advantage in nutrient-poor ecosystems and that this property likely contributed to Grevillea’s evolutionary success.
This could explain the rapid diversification over a relatively short evolutionary time period of Grevillea, an Australian plant genus with 452 recognised species/subspecies and ‘only’ 11 million years of evolutionary history.

The Greater Blue Mountains Area is a deeply incised sandstone tableland that encompasses a million hectares of eucalypt-dominated landscape, just inland from Sydney. This landscape supports an exceptional representation of the taxonomic, physiognomic and ecological diversity that eucalypts have developed: an outstanding illustration of the evolution of plant life. A number of rare and endemic plants, including relict flora such as the Wollemi pine, also occur here.
The geology and geomorphology of 300 metre cliffs, slot canyons and waterfalls, make this a special landscape with many outstandng qualities. The Undercliff Track is just one of many routes that allow access into this remarkable wilderness of outstanding beauty.

Still older fossils document the genus since the Late Oligocene onwards. The genus seems to have originated in the Southern Hemisphere, in the general region of Australia. By the Pliocene, it was probably distributed worldwide:
Gallinula sp. (Early Pliocene of Hungary and Germany)
Gallinula kansarum (Late Pliocene of Kansas, USA)
Gallinula balcanica (Late Pliocene of Varshets, Bulgaria).
Gallinula gigantea (Early Pleistocene of Czech Republic and Israel)
The ancient "Gallinula" disneyi (Late Oligocene—Early Miocene of Riversleigh, Australia) has been separated as genus Australlus.
Even among non-Passeriformes, this genus has a long documented existence. Consequently, some unassigned fragmentary rail fossils might also be from moor- or native-hens. For example, specimen QM F30696, a left distal tibiotarsus piece from the Oligo-Miocene boundary at Riversleigh, is similar to but than and differs in details from "G." disneyi. It cannot be said if this bird—if a distinct species—was flightless. From size alone, it might have been an ancestor of G. mortierii (see also below).
In addition to paleosubspecies of Gallinula chloropus, the doubtfully distinct Late Pliocene to Pleistocene Gallinula mortierii reperta was described, referring to the population of the Tasmanian native-hen that once inhabited mainland Australia and became extinct at the end of the last ice age.[6] It may be that apart from climate change it was driven to extinction by the introduction of the dingo, which as opposed to the marsupial predators hunted during the day, but this would require a survival of mainland Gallinula mortierii to as late as about 1500 BC.
"G." disneyi was yet another flightless native-hen, indicative of that group's rather basal position among moorhens. Its time and place of occurrence suggest it as an ancestor of G. mortierii (reperta), from which it differed mostly in its much smaller size. However, some limb bone proportions are also strikingly different, and in any case such a scenario would require a flightless bird to change but little during some 20 million years in an environment rich in predators. As the fossils of G. disneyi as well as the rich recent and subfossil material of G. mortierii shows no evidence of such a change at all, "G." disneyi more probably represents a case of parallel evolution at an earlier date, as signified by its placement in Australlus.
