With their work at East Durham Yard complete, NS 351 hustles west through downtown Durham. Second out in the consist is one of the AC44C6Ms with the gray mane livery.
The gray wolf (Canis lupus), also known as the timber wolf or western wolf.
In 2013, a genetic study found that the wolf population in Europe was divided along a north-south axis and formed five major clusters. Three clusters were identified occupying southern and central Europe in Italy, the Dinaric-Balkans, the Carpathians. Another two clusters were identified occupying north-central Europe and the Ukrainian steppe. The Italian wolf consisted of an isolated population with low genetic diversity. Wolves from Croatia, Bulgaria, and Greece formed the Dinaric-Balkans cluster. Wolves from Finland, Latvia, Belarus, Poland and Russia formed the north-central Europe cluster, with wolves from the Carpathians cluster coming from a mixture of wolves from the north-central cluster and the Dinaric-Balkans cluster. The wolves from the Carpathians were more similar to the wolves from the Pontic-Caspian Steppe than they were to wolves from north-central Europe. These clusters may have been the result of expansion from glacial refugia, an adaptation to local environments, and landscape fragmentation and the killing of wolves in some areas by humans.
In 2016, two genetic studies of North American gray wolves found that they formed six ecotypes – genetically and ecologically distinct populations separated from other populations by their different type of habitat. These six wolf ecotypes were named West Forest, Boreal Forest, Arctic, High Arctic, Baffin, and British Columbia. The studies found that precipitation and mean diurnal temperature range were the most influential variables. These findings were in accord with previous studies that precipitation influenced morphology and that vegetation and habitat type influenced wolf differences.The local adaptation of a wolf ecotype most likely reflects a wolf's preference to remain in the type of habitat that it was born into.
Gray wolves, or timber wolves, are canines with long bushy tails that are often black-tipped. Their coat color is typically a mix of gray and brown with buffy facial markings and undersides, but the color can vary from solid white to brown or black. Gray wolves look somewhat like a large German shepherd. Wolves vary in size depending on where they live. Wolves in the north are usually larger than those in the south. The average size of a wolf's body is three to five feet long and their tails are usually one to two feet long. Females typically weigh 60 to 100 pounds, and males weigh 70 to 145 pounds.
A rare moment of compassionate cooperation was most appreciated when this Blue-Gray Gnatcatcher actually gave me enough time to grab focus.

Gray Fox in the snow.
Known to the Mayan people as "Gato de Monte" or cat of the mountain, the Gray Fox was believed to be a recent offshoot from the Red Fox. Not so, say the fossil records.
The Gray Fox belongs to a distinct genus, Urocyon, with a separate evolutionary lineage, which branched early from the ancient canids and has existed as it's own branch four to six million years.
The Gray Fox remains the most elusive, and least understood fox species in North America.
Canada's National Bird, at least when the Government of Canada (Ottawa) gets their shit together and makes it official. Very friendly, they will take food right from your hands.
The often heard, but seldom seen catbird... their distinctive cat like calls can be often heard, but they are usually hiding out deep in bushes, rarely seen out in the open.
I hear these birds more often than see them since they love to dive deep into shrubs and tangles of vegetation. This one made a brief appearance out in the open.
CSX K424, with a YN2 paint leader, turns from a northbound train to an eastbound train at the wye in Deshler, Ohio on a gray October afternoon.
Gray-tailed Tattlers are quite rare on Saint Paul Island, AK during this time in May. We were fortunate to see two but they were quite camera shy and flew every time we got even remotely close to them.
Gray Goshawk :: Accipiter novaehollandiae
The Grey Goshawk is a medium-sized bird of prey, with two colour forms. The grey morph has a grey head and upperparts, with white underparts barred grey on the chest. The rounded wings are grey above, white below, and have darker wingtips. The medium length tail is grey above and white below, barred grey. The white morph is pure white all over and is often known as the White Goshawk. Both morphs have a dark red eye and yellow legs and feet.
On a gray winter day NS 212 meets M9G at the South Ave grade crossing in Middlesex, NJ. The scene was so devoid of any meaningful color, black & white seemed the way to go.

NS 4313 AC44C6M
One of the more unusual vehicles to grace the B52 works service to the Omega Development Site north west of Warrington, was this former Brighton and Hove Mercedes Citaro, which operated the evening service on March 1st due to an acute vehicle shortage.
Owned by Gray Line, it was new to London General as MAL109 and worked for Go North East before heading to Brighton.
A young gray fox. It was with an older fox, but I understand that the gray fox leave their young early to fend for themselves. Taken near Montello, Wisconsin.
This great gray owl came in close while hunting well after the sun went down. The light at this time of the evening is referred to as "the blue hour". It's tough to get a wildlife image in this light since it's so dark, but I did manage to get some shots with a tripod. Alberta, Canada. February, 2020.
Amazing hunters, super fast on the branches and hawking insects in the air - these are among my favourite birds to watch.
