White-tailed Deer (Odocoileus virginianus)

White-tailed Deer are found throughout North America; from southern Canada, through mainland United States, and reaching Central America as far as Bolivia. This ubiquitous nature likely has led to the fact that 11 States proclaim White-tailed Deer to be their State Animal. In North America, there are 16 subspecies of White-tailed Deer differentiated by size, coloration, geographic location, and biological differences.


White-tailed Deer:
  • run up to 40 mph, and jump 8 - 9 foot fences.
  • range in size from 100 - 300 pounds and stand about 3.5 feet at the shoulder, depending on sex, age, geographic location, and general nutrition.
  • have a lifespan of about 10 years in the wild.
  • mate between October and December; gestation is 200 days, and healthy does over one-year old generally produce 2 fawns between May and June.
  • are herbivores (eat vegetation only).
  • are ruminants; i.e. they have 4 stomachs to aide in the digestion of all types of vegetation.
Beyond the basics, White-tailed Deer have exhibited dramatic population changes both on Block Island and on the mainland. It is estimated that before Europeans arrived, there were 23 to 40 million White-tailed Deer in North America. However, numbers of White-tailed Deer were greatly reduced throughout the U.S until the mid-20th century: and by 1900 White-tailed Deer were nearly eliminated in the northeastern United States. Today the White-tailed Deer population in the U.S. is estimated to be 14-20 million. In the northeast U.S., the number is believed to be 3 million; a number previously unattained.

Facts about White-tailed Deer on Block Island:
  • White-tailed Deer are one of only 5 types of mammals that live on Block Island.
  • Four White-tailed Deer were introduced on Block Island on February 24, 1967.
  • The RI Fish and Wildlife estimated that the deer population had grown to 700 by 1994.
  • According to local hunters, the number of White-tailed Deer on Block Island after the close of the 2004-2005 hunting season on February 18, 2005 is about 225, or 20.5 deer per square mile.
  • State of RI density: 7.1 deer per square mile
  • Hunters are the only predators of deer on BI. During the 2004-2005 hunting season, 166 deer were taken by archery and shotgun hunters. An additional 13 deer were killed by motor vehicles, dogs, and unknown causes.
  • Given the generally healthy status of the BI herd, 100+ females can be expected to give birth to 150 - 200 fawns in May - June 2005.
The following is taken from the Town of New Shoreham Town Council Records - Books L, DD, and EE. The members of Town Council in 1967 were: Samuel Mott, president, John C. Dodge, Harold R. Westcott, Lew Gaffett, and Lester Littlefield.

January 14, 1967
"Thomas C. Littlefield informed the Town Council of a recent conversation with Mr. Thomas J. Wright of the Division of Fish and Game relative to the possibility of obtaining deer for Block Island. Mr. Littlefield learned that the State had a supply on hand at this time and if the Council made a request for some, there was a good possibility some could be had. The Council considered the matter and thereafter a motion was made, seconded and unanimously voted to request two (2) pairs of deer for the Island."

February 6, 1967
"Following the last Council meeting, the Clerk wrote to Mr. Thomas J. Wright on behalf of the Council asking for two (2) pairs of deer for the Island. A reply from Mr. Wright on February 2, 1967 was read, acknowledging receipt of the letter and stating that it appears that they may be able to attempt the project next week and the deer should soon be delivered to the Island."

March 6, 1967
"A written complaint in regard to possible future deer damage to plants, flowers and gardens [was] received from Maud F. Messer."

March 13, 1967
"Town librarian Beatrice Ball Dodge asked about an ordinance regulating the shooting of deer on the Island."

September 17, 1997
The Town Council voted to set a goal to "...substantially decrease the number of deer to ten deer per square mile on the Island."

January 4, 1999
The Town Council voted to "...adopt the complete elimination of the deer population as a Town goal."
