Northern Pintail
These are mostly transient birds, although a few do breed throughout the Okanagan. They winter in large numbers in the bays and fields of California, and many areas are set aside for waterfowl in that region. During February and March these birds migrate north, mainly to Alaska, Alberta and the Cariboo region and Peace River lowlands of B.C. In the fall, freezing weather and ice will force them to move south. They are a popular bird for the duck hunters.
As the name suggests the bird has a needle like pointed tail and combined with longish wings and a long slender neck marked with a white stripe is easily recognized. The male measures 28" in length, while the female, 21". They are very elegant in appearance and are often referred to as the "greyhound" of duck family. The birds nest in open grasslands near ponds with an average clutch of 9 eggs. They feed on seeds, larvae and aquatic insects.
Green Winged Teal
This is our smallest dabbling duck, with a short body, measuring only 14". It has a rounded rufous and green head; a narrow bill, and a brilliant green area on the trailing edge of the wing, [hence it's name]; a white belly and a white bar on the under shoulder [seen in flight]. The green on the wing is easier to see in the non-breeding season as it contrasts with a dull coloured body. These birds are found in all parts of the Northern Hemisphere and are very hardy. They feed in shallow marshy or muddy ponds feeding mainly on seeds. The female's call is a feeble 'quack'. Nests are often found at the base of a tree and usually not too far from fresh water. All teal are subject to predation by falcons, goshawks and eagles.
Blue Winged Teal
This bird is a little larger than the green winged teal. It sports a large chalky blue patch on the forewing. It can also be identified by a white facial crescent. It is less hardy than the green winged teal, arriving later in spring and leaving earlier in the fall to winter in Argentina. It prefers warmer ponds and hot summers, feeding mainly on seeds of aquatic plants. The nest is built on sedge or grass at the water's edge and averages 10 eggs. It should be mentioned that the female of the duck species uses the down feathers from the breast to line her nest.
Cinnamon Teal
This bird is slightly larger again at 15-17" than the Blue Winged Teal. A dark brilliant chestnut body is very distinctive. It also has a blue pale patch on the forewing and a heavy looking bill. It frequents marshes and ponds in S.W. Canada and W.U.S. in summer and enjoys winters in S. America. The nest is built in tall grass near water and averages 9-13 eggs. The young feed on worms and insects, before progressing to plants.
All dabbling ducks jump into the air from water or land as opposed to diving ducks that skitter along the water before they can get airborne.
