The Sign on North Lakeshore


This is the road as it approaches Turtle Log Bridge. The sign was just before this bridge.

The Sign Read:

Let No Man Say And Say With Shame
That All Was Beauty Here
Before You Came

That was what the old wood sign read, posted on the polls in the little park in front of the bench on north lakeshore drive, just across the Lakeshore drive road from Jack Gillespie’s house on Mirror Lake in Browns Mills (NJ).

Jack’s a story himself, but he must have had to look at that sign every day, while I only saw it when I was taking a ride around the lake. I don’t know how long it was there but I remember reading the sign for the first time when I was a kid in the back seat during an after dinner pop sickle ride into town.

But it wasn’t there one day, and when somebody else mentioned it, we promised each other that we would have it replaced, as the two wood poles were still there, it was just the sign that was missing.

TT found an old photo of the sign and somebody posted it on the Facebook page – You must be from Browns Mills if you remember....the sign that isn’t there anymore.

Muscovy Ducks


While I took this photo a few years ago, the same group of Muscovys that live near the first lagoon on South Lake Shore Drive in Browns Mills just had another brood - in late November.


Muscovy Duck (Cairina moschata) is a large duck which is native to Mexico and Central and South America. A small wild population reaches into the United States in the lower Rio Grande Valley of Texas. There also are feral breeding populations in North America in and around public parks in nearly every state of the USA and in the Canadian provinces; feral populations also exist in Europe. Although the Muscovy Duck is a tropical bird, it adapts to icy and snowy conditions down to –12°C (10°F) and below without ill effects.[2][3] In general, "Barbary Duck" is the usual term for C. moschata in a culinary context.


All Muscovy Ducks have long claws on their feet and a wide flat tail. In the domestic drake (male), length is about 86 cm (34 in) and weight is 4.6–6.8 kg (10–15 lb), while the domestic hen (female) is much smaller, at 64 cm (25 in) in length and 2.7–3.6 kg (6.0–7.9 lb) in weight. Large domesticated males often weigh up to 8 kg (18 lb), and large domesticated females up to 5 kg (11 lb). One male of an Australian breed weighed about 10 kg (22 lb).[4]
The true wild Muscovy Duck, from which all domesticated Muscovys originated, is blackish, with large white wing patches. Length can range from 66 to 84 cm (26 to 33 in), wingspan from 137 to 152 cm (54 to 60 in) and weight from 1.1–4.1 kg (2.4–9.0 lb) in wild Muscovys. On the head, the wild male has short crest on the nape. The bill is black with a speckling of pale pink. A blackish or dark red knob can be seen at the bill base, and the bare skin of the face is similar to that in color. The eyes are yellowish-brown. The legs and webbed feet are blackish. The wild female is similar in plumage, but is also much smaller, and she has feathered face and lacks the prominent knob. The juvenile is duller overall, with little or no white on the upperwing.[5] Domesticated birds may look similar; most are dark brown or black mixed with white, particularly on the head.[6] Other colors such as lavender or all-white are also seen. Both sexes have a nude black-and-red or all-red face; the drake also has pronounced caruncles at the base of the bill and a low erectile crest of feathers.[3]
C. moschata ducklings are mostly yellow with buff-brown markings on the tail and wings. Some domesticated ducklings have a dark head and blue eyes, others a light brown crown and dark markings on their nape. They are agile and speedy precocial birds.
The drake has a low breathy call, and the hen a quiet trilling coo.
The karyotype of the Muscovy Duck is 2n=80, consisting of three pairs of macrochromosomes, 36 pairs of microchromosomes, and a pair of sex chromosomes. The two largest macrochromosome pairs are submetacentric, while all other chromosomes are acrocentric or (for the smallest microchromosomes) probably telocentric. The submetacentric chromosomes and the Z (female) chromosome show rather little constitutive heterochromatin (C bands), while the W chromosomes are at least two-thirds heterochromatin.[7]
Male Muscovy Ducks have spiralled penises which can become erect to 20 cm in one third of a second. Females have cloacas that spiral in the opposite direction to try to limit forced copulation by males.[8]


The term "Muscovy" means "from the Moscow region", but these ducks are neither native there nor were they introduced there before they became known in Western Europe. It is not quite clear how the term came about; it very likely originated between 1550 and 1600, but did not become widespread until somewhat later.

In one suggestion, it has been claimed that the Company of Merchant Adventurers to New Lands traded these ducks to Europe occasionally after 1550;[9] this chartered company became eventually known as the Muscovy Company or "Muscovite Company" so the ducks might thus have come to be called "Muscovite Ducks" or "Muscovy Ducks" in keeping with the common practice of attaching the importer's name to the products they sold.[9] But while the Muscovite Company initiated vigorous trade with Russia, they hardly, if at all, traded produce from the Americas; thus they are unlikely to have traded C. moschata to a significant extent.

Alternatively – just as in the "turkey" bird (which is also from America), or the "guineafowl" (which are not limited to Guinea) – "Muscovy" might be simply a generic term for a hard-to-reach and exotic place, in reference to the singular appearance of these birds. This is evidenced by other names suggesting the species came from lands where it is not actually native, but from where much "outlandish" produce was imported at that time (see below). A more recent parallel is the "Persian" cat, which resembles cats from Greater Khorasan and Ankara, but was actually bred in England.[10]

Yet another view – not incompatible with either of those discussed above – connects the species with the Muisca, a Native American nation in today's Colombia. The duck is native to these lands too, and it is likely that it was kept by the Muisca as a domestic animal to some extent. It is conceivable that a term like "Muisca duck", hard to comprehend for the average European of those times, would be corrupted into something more familiar.
The Miskito Indians of the Miskito Coast in Nicaragua and Honduras relied heavily on this domestic species. The ducks may have been named after this region.

The species was first scientifically described by Carl Linnaeus in his 1758 edition of Systema Naturae as Anas moschata,[11] literally meaning "musk duck". His description only consists of a curt but entirely unequivocal [Anas] facie nuda papillosa ("A duck with a naked and carunculated face"), and his primary reference is his earlier work Fauna Svecica.[12] But Linnaeus refers also to older sources, and therein much information on the origin of the common name is found.
Conrad Gessner is given by Linnaeus as a source, but the Historiae animalium mentions the Muscovy Duck only in passing.[13] Ulisse Aldrovandi[14] discusses the species in detail, referring to the wild birds and its domestic breeds variously as anas cairina, anas indica or anas libyca – "Duck from Cairo", "Indian Duck" (in reference to the West Indies) or "Libyan Duck". But his anas indica (based, like Gessner's brief discussion, ultimately on the reports of Christopher Columbus's travels) also seems to have included another species,[15] perhaps a whistling-duck (Dendrocygna). Already however the species is tied to some more or less nondescript "exotic" locality – "Libya" could still refer to any place in Northern Africa at that time – where it did not natively occur. Francis Willughby[16] discusses "The Muscovy Duck" as anas moschata and expresses his belief that Aldrovandi's and Gessner's anas cairina, anas indica and anas libyca (which he calls "The Guiny Duck", adding another mistaken place of origin to the list) refer to the very same species. Finally, John Ray clears up much of the misunderstanding by providing a contemporary explanation for the bird's etymology:
"In English, it is called The Muscovy-Duck, though this is not transferred from Muscovia [the New Latin name of Muscovy], but from the rather strong musk odour it exudes."[17]
Linnaeus came to witness the birds' "gamey" aroma first-hand, as he attests in the Fauna Svecica and again in the travelogue of this 1746 Västergötland excursion.[18] Similarly, the Russia

name of this species, muskusnaya utka (Мускусная утка), means "musk duck" – without any reference to Moscow – as do the Bokmål moskusand, Dutch muskuseend, Finnish myskisorsa, French canard musqué, German Moschusente, Italian anatra muschiata, Spanish pato almizclado and Swedish myskand. In English however, Musk Duck refers to the Australian species Biziura lobata.

In some regions the name Barbary Duck is used for domesticated and "Muscovy Duck" for wild birds; in other places "Barbary Duck" refers specifically to the dressed carcass, while "Muscovy Duck" applies to living C. moschata, regardless of whether they are wild or domesticated. In general, "Barbary Duck" is the usual term for C. moschata in a culinary context.

This species was formerly placed into the paraphyletic "perching duck" assemblage, but subsequently moved to the dabbling duck subfamily (Anatinae). Analysis of the mtDNA sequences of the cytochrome b and NADH dehydrogenase subunit 2 genes,[19] however, indicates that it might be closer to the genus Aix and better placed in the shelduck subfamily Tadorninae. In addition, the other species of Cairina, the rare White-winged Duck (C. scutulata), seems to belong into a distinct genus. The generic name Cairina, meanwhile, traces its origin to Aldr
Aldrovandi, and ultimately to the mistaken belief that the birds came from Egypt: translated, the current scientific name of the Muscovy Duck means "the musky one from Cairo".

[edit]Ecology

This non-migratory species normally inhabits forested swamps, lakes, streams and nearby grassland and farm crops,[20] and often roosts in trees at night. The Muscovy Duck's diet consists of plant material obtained by grazing or dabbling in shallow water, and small fish, amphibians, reptiles, crustaceans, insects, and millipedes. [21] This is a somewhat aggressive duck; males often fight over food, territory or mates. The females fight with each other less often. Some adults will peck at the ducklings if they are eating at the same food source.
The Muscovy Duck has benefited from nest boxes in Mexico, but is somewhat uncommon in much of the east of its range due to excessive hunting. It is not considered a globally threatened species by the IUCN however, as it is widely distributed.[22]

[edit]Reproduction
This species, like the Mallard, does not form stable pairs. They will mate on land or in water (note the submerged female in the image below). Domesticated Muscovy Ducks can breed up to three times each year.

The hen lays a clutch of 8-16 white eggs, usually in a tree hole or hollow, which are incubated for 35 days. The sitting hen will leave the nest once a day from 20 minutes to one and a half hours, and will then defecate, drink water, eat and sometimes bathe. Once the eggs begin to hatch it may take 24 hours for all the chicks to break through their shells. When feral chicks are born they usually stay with their mother for about 10–12 weeks. Their bodies cannot produce all the heat they need, especially in temperate regions, so they will stay close to the mother especially at night.

Often, the drake will stay in close contact with the brood for several weeks. The male will walk with the young during their normal travels in search for food, providing protection. Anecdotal evidence from East Anglia, UK suggests that, in response to different environmental conditions, other adults assist in protecting chicks and providing warmth at night. It has been suggested that this is in response to local efforts to cull the eggs, which has led to an atypical distribution of males and females as well as young and mature birds.

For the first few weeks of their lives, Muscovy duckling feed on grains, corn, grass, insects, and almost anything that moves. Their mother instructs them at an early age how to feed.

Feral Muscovy Ducks can breed near urban and suburban lakes and on farms, nesting in tree cavities or on the ground, under shrubs in yards, on condominium balconies, or under roof overhangs. Some feral populations, such as that in Florida, have a reputation of becoming nuisance pests on occasion.[23] At night they often sleep at water, if there is a water source available, to flee quickly from predators if awoken. A small population of Muscovy Ducks can also be found in Ely, Cambridgeshire, UK, where they are considered a pest and culled by the local council.

In the US, Muscovy Duccks are considered an invasive species. An owner may raise them for food production only (not for hunting). Similarly, if the ducks have no owner, 50CFR Part 21 allows the removal or destruction of the Muscovy ducks, their eggs and nests anywhere in the United States outside of Hidalgo, Starr, and Zapata counties in Texas where they are considered indigenous. The population in southern Florida is considered, with a population in the several thousands, to established there enough be is considered "countable" for bird watchers.[24]

Legal methods to restrict breeding include not feeding these ducks, deterring them with noise or by chasing, and finding nests and vigorously shaking the eggs to render them non-viable. Returning the eggs to the nest will avoid re-laying as the female would if the clutch were removed.
Recent legislation in the USA prohibits trading of Muscovy Ducks and plans for eradication are in order to solve nuisance problems.[21]
