Awww, loving the almost daily surprises of all the new Spring growth popping up around the farm.
English bluebells (Hyacinthoides non-scripta) are an introduced species in the Pacific Northwest and other parts of Canada. They date back to the early 1500s and are native to England and France.
In the United Kingdom, the bluebell is protected under the “Wildlife and Countryside Act, 1981”. Landowners are prohibited from removing common bluebells on their land and it is a criminal offence to remove the bulbs of wild common bluebells. Source Wikipedia.
These fragrant spring bluish purplish delights reach heights of 12 inches and make beautiful cut flowers.
Driving from Chablis to Dijon, you pass by some signs to Source de la Seine. Having never been to the headwaters of a major river, the opportunity could not be passed up, especially after we passed the first turnoff and a second opportunity presented itself.
There, in woods off the D103 road approximately 2 km Southeast by east of the cluster of buildings in Saint-Germaine, or 3 km East by south of the cluster of buildings in Blessey, you feel as though you've been transported to the set of the French version of Deliverance. The flotilla of ATV's blasting out of the forest did not help alleviate the concern.
Nonetheless, there was something spiritual to stand on the very first bridge across the River Seine, even though you could basically step across it anyway.

The Grand Canyon is a steep-sided canyon carved by the Colorado River in Arizona, United States. The Grand Canyon is 277 miles (446 km) long, up to 18 miles (29 km) wide and attains a depth of over a mile (6,093 feet or 1,857 meters).
The canyon and adjacent rim are contained within Grand Canyon National Park, the Kaibab National Forest, Grand Canyon–Parashant National Monument, the Hualapai Indian Reservation, the Havasupai Indian Reservation and the Navajo Nation. The surrounding area is contained within the Baaj Nwaavjo I'tah Kukveni – Ancestral Footprints of the Grand Canyon National Monument. President Theodore Roosevelt was a major proponent of the preservation of the Grand Canyon area and visited it on numerous occasions to hunt and enjoy the scenery.
Nearly two billion years of Earth's geological history have been exposed as the Colorado River and its tributaries cut their channels through layer after layer of rock while the Colorado Plateau was uplifted. While some aspects about the history of incision of the canyon are debated by geologists, several recent studies support the hypothesis that the Colorado River established its course through the area about 5 to 6 million years ago. Since that time, the Colorado River has driven the down-cutting of the tributaries and retreat of the cliffs, simultaneously deepening and widening the canyon.
For thousands of years, the area has been continuously inhabited by Native Americans, who built settlements within the canyon and its many caves. The Pueblo people considered the Grand Canyon a holy site, and made pilgrimages to it. The first European known to have viewed the Grand Canyon was García López de Cárdenas from Spain, who arrived in 1540.

SFRD 12246 on display at the Shafter Depot Museum, 150 Central Valley Hwy / CA 43 ~ Shafter, CA
Note - The Santa Fé Refrigerator Despatch [reporting mark SFRD] was a railroad refrigerator car line established as a subsidiary of the Atchison, Topeka & Santa Fé Railway in 1884 to carry perishable commodities. Though the line started out with a mere 25 ventilated fruit cars and 8 ice-cooled refrigerator cars, by 1910 its roster had swollen to 6,055 total units [compared to the 8,100 units its largest competitor, the Pacific Fruit Express, operated].
As of 1929 the line was carrying some 43 percent of California's citrus crop, most of which travelled aboard its "Green Fruit Express" refrigerator car special. Some 100,000 produce loads were shipped from the fields of Arizona and California to East Coast markets each growing season.

SHAFTER DEPOT: This building originally located 4 blocks southeast of this site and was opened for use and dedicated October 11, 1917. Until it closed in 1978, this building served as Shafter’s gateway to the world as the Mail, Western Union Telegraph, Express, Freight and Rail passengers passed through it’s doors. The concern for preservation of this building resulted in the formation of the Shafter Historical Society in July of 1979. In March 1980, the society accepted the gift of the depot from the Atchison, Topeka & Santa Fé Railway Co. and moved it to this site donated by the Harlan Wilson Family and by the S.A. Camp Ginning Co. with much public support, the society restored the building to it’s original format and dedicated it for many more years of service as the Shafter Museum October 9th, 1982.
This property has been placed on the National Register of Historic Places by the United States Department of Interior.

Most of the stream along the Rock Canyon hike is trapped in underground pipes. There is one small section in which the water gushes out, forms a natural looking creek for about 200 feet, and then returns underground. This is the waterspout at the head of the creek.

The mandarin duck (Aix galericulata) is a perching duck species found in East Asia. It is medium-sized, at 41–49 cm (16–19 in) long with a 65–75 cm (26–30 in) wingspan. It is closely related to the North American wood duck, the only other member of the genus Aix. Aix is an Ancient Greek word used by Aristotle to refer to an unknown diving bird, and galericulata is the Latin for a wig, derived from galerum, a cap or bonnet.
The adult male is a striking and unmistakable bird. It has a red bill, large white crescent above the eye and reddish face and "whiskers". The breast is purple with two vertical white bars, and the flanks ruddy, with two orange "sails" at the back. The female is similar to female wood duck, with a white eye-ring and stripe running back from the eye, but is paler below, has a small white flank stripe, and a pale tip to its bill.
Both the males and females have crests, but the crest is more pronounced on the male.
Like many other species of ducks, the male undergoes a moult after the mating season into eclipse plumage. When in eclipse plumage, the male looks similar to the female, but can be told apart by their bright yellow-orange beak, lack of any crest, and a less-pronounced eye-stripe.
Mandarin ducklings are almost identical in appearance to wood ducklings, and very similar to mallard ducklings. The ducklings can be distinguished from mallard ducklings because the eye-stripe of mandarin ducklings (and wood ducklings) stops at the eye, while in mallard ducklings it reaches all the way to the bill.
The hooded crow (Corvus cornix) (also called hoodie is a Eurasian bird species in the Corvus genus. Widely distributed, it is also known locally as Scotch crow and Danish crow. In Ireland it is called grey crow, just as in the Slavic languages and in Danish. In German it is called "mist crow" ("Nebelkrähe"). Found across Northern, Eastern, and Southeastern Europe, as well as parts of the Middle East, it is an ashy grey bird with black head, throat, wings, tail, and thigh feathers, as well as a black bill, eyes, and feet. Like other corvids, it is an omnivorous and opportunistic forager and feeder.
It is so similar in morphology and habits to the carrion crow (Corvus corone), for many years they were considered by most authorities to be geographical races of one species. Hybridization observed where their ranges overlapped added weight to this view. However, since 2002, the hooded crow has been elevated to full species status after closer observation; the hybridisation was less than expected and hybrids had decreased vigour. Within the hooded crow species, four subspecies are recognized, with one, the Mesopotamian crow, possibly distinct enough to warrant species status itself.
Except for the head, throat, wings, tail, and thigh feathers, which are black and mostly glossy, the plumage is ash-grey, the dark shafts giving it a streaky appearance. The bill and legs are black; the iris dark brown. Only one moult occurs, in autumn, as in other crow species. The male is the larger bird, otherwise the sexes are alike. Their flight is slow and heavy and usually straight. Their length varies from 48 to 52 cm (19 to 20 in). When first hatched, the young are much blacker than the parents. Juveniles have duller plumage with bluish or greyish eyes and initially a red mouth. Wingspan is 98 cm (39 in) and weight is on average 510 g.
The mallard or wild duck (Anas platyrhynchos) is a dabbling duck which breeds throughout the temperate and subtropical Americas, Europe, Asia, and North Africa, and has been introduced to New Zealand, Australia, Peru, Brazil, Uruguay, Argentina, Chile, the Falkland Islands and South Africa. This duck belongs to the subfamily Anatinae of the waterfowl family Anatidae.
The male birds (drakes) have a glossy green head and are grey on wings and belly, while the females (hens or ducks) have mainly brown-speckled plumage. Both sexes have an area of white-bordered black speculum feathers which commonly also include iridescent blue feathers especially among males. Mallards live in wetlands, eat water plants and small animals, and are social animals preferring to congregate in groups or flocks of varying sizes. This species is the main ancestor of most breeds of domesticated ducks.
The mallard is a medium-sized waterfowl species although it is often slightly heavier than most other dabbling ducks. It is 50–65 cm (20–26 in) long (of which the body makes up around two-thirds), has a wingspan of 81–98 cm (32–39 in),[16] and weighs 0.72–1.58 kg (1.6–3.5 lb). Among standard measurements, the wing chord is 25.7 to 30.6 cm (10.1 to 12.0 in), the bill is 4.4 to 6.1 cm (1.7 to 2.4 in) and the tarsus is 4.1 to 4.8 cm (1.6 to 1.9 in).
The breeding male mallard is unmistakable, with a glossy bottle-green head and white collar which demarcates the head from the purple-tinged brown breast, grey brown wings, and a pale grey belly. The rear of the male is black, with the dark tail having white borders. The bill of the male is a yellowish orange tipped with black while that of the female is generally darker ranging from black to mottled orange. The female mallard is predominantly mottled with each individual feather showing sharp contrast from buff to very dark brown, a coloration shared by most female dabbling ducks, and has buff cheeks, eyebrow, throat and neck with a darker crown and eye-stripe.
Owing to their highly 'malleable' genetic code, Mallards can display a large amount of variation, as seen here with this female, who displays faded or 'apricot' plumage.
Both male and female mallards have distinct iridescent purple blue speculum feathers edged with white, prominent in flight or at rest, though temporarily shed during the annual summer moult. Upon hatching, the plumage colouring of the duckling is yellow on the underside and face (with streaks by the eyes) and black on the back (with some yellow spots) all the way to the top and back of the head. Its legs and bill are also black. As it nears a month in age, the duckling's plumage will start becoming drab, looking more like the female (though its plumage is more streaked) and its legs will lose their dark grey colouring. Two months after hatching, the fledgling period has ended and the duckling is now a juvenile. Between three and four months of age, the juvenile can finally begin flying as its wings are fully developed for flight (which can be confirmed by the sight of purple speculum feathers). Its bill will soon lose its dark grey colouring and its sex can finally be distinguished visually by three factors. The bill colouring is yellow in males, black and orange for females. The breast feathers are reddish-brown for males, brown for females. The centre tail feather is curled for males (called a drake feather), straight for females.[citation needed]
During the final period of maturity leading up to adulthood (6–10 months of age), the plumage of female juveniles remains the same while the plumage of male juveniles slowly changes to its characteristic colours.[citation needed] This plumage change also applies to adult mallard males when they transition in and out of their non-breeding eclipse plumage at the beginning and the end of the summer moulting period. The adulthood age for mallards is 14 months and the average life expectancy is 3 years, but they can live to twenty.
In captivity, domestic ducks come in wild-type plumages, white, and other colours. Most of these colour variants are also known in domestic mallards not bred as livestock, but kept as pets, aviary birds, etc., where they are rare but increasing in availability.
A noisy species, the female has a deeper quack stereotypically associated with ducks. Male mallards also make a sound which is phonetically similar to that of the female, but it is a deep and raspy sound which can also sound like mek or whak. When incubating a nest, or when offspring are present, Females vocalise differently, making a call which sounds like a truncated version of the usual quack. They will also hiss if the nest or their offspring are threatened or interfered with.
The mallard is a rare example of both Allen's Rule and Bergmann's Rule in birds. Bergmann's Rule, which states that polar forms tend to be larger than related ones from warmer climates, has numerous examples in birds. Allen's Rule says that appendages like ears tend to be smaller in polar forms to minimize heat loss, and larger in tropical and desert equivalents to facilitate heat diffusion, and that the polar taxa are stockier overall. Examples of this rule in birds are rare, as they lack external ears. However, the bill of ducks is very well supplied with blood vessels and is vulnerable to cold.[citation needed]
Due to the malleability of the mallard's genetic code, which gives it its vast interbreeding capability, mutations in the genes that decide plumage colour are very common and have resulted in a wide variety of hybrids such as Brewer's duck (mallard × gadwall, Anas strepera).
