  • Kyle Sams

2
Taxonomy
  • Kingdom Animalia
  • Phylum Chordata
  • Class Aves
  • Order Anseriformes
  • Family Anatidae
  • Genus Anas
  • Species acuta

  • Chocolate brown head
  • White neck, breast belly, white finger up back
    of neck
  • Pale grey bill, with black stripe down center
  • Gray flanks back, w/ black centers to back
    feathers
  • Black under-tail coverts
  • Long black central tail feathers
  • Green speculum w/ white rear border chestnut
    forward border

  • Avg. weight is 1.91 lbs.
  • Tan head neck
  • Mottled tan dark brown body, paler on belly
  • Grey bill
  • Brown speculum white rear border

5
Sub-SpeciesEatons Pintails
  • Kerguelen Pintail (Anas eatoni eatoni)
  • Confined to Kerguelen islands off S. America
  • Crozet Pintail (Anas eatoni drygalskyi)
  • Confined to Crozet islands, also off S. America

6
Pintail Migration
  • Among the first ducks to migrate
  • Most migrating through Cali.
  • Others using the Mississippi flyway, to LA, TN,
    AL, MS
  • Also common visitors in Central America

7
Breeding Range
  • Breed from Alaska, central Canadian Arctic,
    Western Greenland, central USA
  • Boreal forest
  • Alaskan coastal areas
  • Prairie potholes

8
Non-Breeding Range
  • Mostly central California, Mexico Gulf coasts,
    Texas panhandle, some on Atlantic coast
  • Over ½ migrate through Cali.

9
Northern Pintail Range
10
Mating
  • Monogamous
  • Same pair mate for life
  • Sexually mature at 1 year old
  • Mate in late April
  • As late as the end of July

11
Pintail Breeding Pairs
12
  • The breeding pair numbers was obtained by the
    Black Duck Joint Venture helicopter survey

13
Nesting
  • Among the first to Nest
  • Nests in open country, w/ shallow, seasonal
    wetlands, low vegetation
  • Copulation takes place in the water
  • Nests is a scrape in ground in brush/grass, lined
    w/ grass down usually not near water
  • Hen incubates eggs alone
  • Usually takes 21-25 days

14
Young
  • Clutch size is usually 8, range 3-14
  • Precocial young
  • Fledge in 6-7 weeks
  • Around ¾ live to fledge
  • Half of those live to breed
  • About 37.5

15
Feeding Characteristics
  • Pintails are DABBLERS
  • Upend while in the water to feed
  • Omnivorous
  • Feed on seeds, nutlets of aquatic plants, also
    eats mollusks, crabs, worms, fairy shrimp,
    other aquatic insects
  • Insects are more important to females during
    pre-laying laying periods

16
Predation
  • People are 1
  • Coyotes
  • Skunks
  • Gulls, crows, magpies
  • Badgers
  • Raccoons

17
Population History
  • Pop. depends on wet-dry cycle
  • In 1955, the breeding pop. was around 6 million
  • Fluctuating between 2 10 million
  • In the 1970s pops recovered when the wetland
    were good, but fell when prairies were dry
    wetland conditions were poor
  • Agriculture has cause most of the problems
  • These factors combined have caused declining
    pintail population since the 1980s

18
Conservation Status
  • Protected by the Migratory Bird Treaty Act
  • Global status is at G5, secure
  • Not endangered, pop. Are lower than desired
  • N. American pop. was around 6 million
  • Reduced to about 2 million birds according to GDNR

19
Northern Pintail Distribution
20
Management
  • Protect restore wetlands
  • Adequate migration wintering habitats must be
    protected, restored, enhanced
  • Protect northern boreal tundra habitats
  • Develop farm programs compatible w/ pintail life
    style
  • Manage for moist soil to stimulate the growth of
    native plants
  • Manage for available cover
  • Cut back on harvest
  • Proper use of fertilizers, pesticides,
    herbicides

21
Economical Importance
  • One of the most sought after ducks by duck
    hunters
  • Damage grain crops and cost farmers money

22
Interesting Facts
  • Range over more of the Earth than any other
    waterfowl
