Organic Heirloom Carrots

The World Carrot Museum (yes) - a virtual museum that attempts to collect and present information on all aspects of carrots. The museum does not currently have a brick and mortar existence but operates only as a website. It was initiated and continues to be curated by John Stolarczyk of Skipton, England.

"The Wild Carrot is the progenitor (wild ancestor) of the domestic carrot. It is clear that the Wild Carrot and Domestic Carrot are not the same species and both co-exist in the modern world. It is a popular myth that domestic carrot was developed from Wild Carrot, probably because of its similar smell and taste. Botanists have failed to develop an edible vegetable from the wild root and when cultivation of garden carrots lapses a few generations, it reverts to another ancestral type, a species that is quite distinct.

Wild Carrot is indigenous to Europe and parts of Asia and, from archaeological evidence, seeds have been found dating since Mesolithic times, approximately 10000 years ago. One cannot imagine that the root would have been used at that time, but the seeds are known to be medicinal and it is likely the seeds were merely gathered rather than actually cultivated.

Wild carrot has a small, tough pale fleshed bitter white root; modern domestic carrot has a swollen, juice sweet root, usually orange. Carrots originated in present day Afghanistan about 5000 years ago, probably originally as a purple or yellow root like those pictured here. Nature then took a hand and produced mutants and natural hybrids, crossing both with cultivated and wild varieties. It is considered that purple carrots were then taken westwards where it is thought yellow mutants and wild forms crossed to produce orange. Finally some motivated Dutch growers took these mutant orange carrots under their horticultural wings and developed them to be sweeter and more practical. It's a long story."

To learn more about the wonders of carrots, carrot crafts, recipes, art or musical instruments, be sure to visit the carrot museum.

Male Belted Kingfisher on piling
Megaceryle alcyon
Budd Inlet
Olympia, WA

February 11, 2011
From Seattle Audubon's Birdweb:
Belted Kingfishers perch or hover over open water, watching for prey. Once prey is sighted, they dive headfirst into the water and seize it with their bills. Typically prey is taken near the surface, and the birds do not submerge themselves completely. Belted Kingfishers are highly territorial and vigorously defend their territories. Their most common call is a dry rattle, often given in flight.

Belted Kingfishers almost always take food from the water, feeding predominantly on small fish. They will also prey on crayfish, frogs, tadpoles, and other aquatic dwellers.

If you are interested in birding in Downtown Olympia, check out the Black Hills Audubon website for information on the best spots and directions.

Barrow's Goldeneye diving for Mussels
Sequence of 3 shots of 1 bird
Woodard Bay Natural Resources Conservation Area
Washington State DNR
Olympia, WA

February 8, 2011
From Seattle Audubon's Birdweb:
Barrow's Goldeneyes are diving ducks, and whole groups of goldeneyes will dive at the same time. They forage around pilings, and most of their foraging is under water. Barrow's Goldeneyes are aggressive and territorial, even more so than Common Goldeneyes. 

A wildlife sanctuary only minutes from downtown Olympia, this site protects habitat ranging from shoreline to wetlands to mature second growth forest on 800 acres. The site has a rich and varied human history, ranging from Native American use to early settlement of southern Puget Sound through the logging era.

Woodard Bay provides habitat for shorebirds and songbirds, harbor seals, river otters, bald eagles, a maternity colony of bats, and one of the most significant heron rookeries in the state.
