Development of wind power, oil production and utility corridors in the western part of North Dakota has altered the quiet pastureland habitat associated with eagles, hawks and various avian species. This "human intrusion" has been attributed as the main cause of a recent decline in their populations by the US Fish and Wildlife Service.
As a result, field surveys for raptor or various other avian species are increasingly required as part of regulatory permitting activities. They include a field walk and/or aerial study for nesting birds prior to any on-the-ground activities to document the presence (or absence) of migratory birds, eggs and active nests.
Helicopter Arriving at "Keitu Base"
Aerial surveys are generally conducted between March 1 and May 15 before leaf out so that nests are visible. Depending on findings, contruction activites could be limited to "non-nesting" times of the year.
Surveys attempt to identify and document the presence of migratory birds, eggs and active nests. Of particular interest are golden eagles and bald eagles. Raptors — which include owls, eagles, vultures, hawks and falcons — all have the same physical characteristics in common; a hooked beak, strong, sharp claws or talons, keen eyesight and all are carnivorous. North Dakota boasts 31 different raptor species; from the majestic bald eagle, to the petite and colorful American kestrel. By far, the most abundant species of raptor in North Dakota is the red-tailed hawk.
Keitu's North Dakota based staff are familiar with wildlife species indigenous to the state. We have established relationships with Federal and state agencies and are prepared to complete the necessary surveys in the most productive and expediant manner.
Typical Construction Limitations:
US Fish and Wildlife Service typically recommends a raptor survey 5 days before construction if that occurs in the breeding season of February to July. Schedule construction for late summer or fall/early winter as to not disrupt waterfowl during their February 1 to July 15 breeding season.
Construction is recommended to take place from September 1 to April 1 and not within one half mile of known or suspected nesting wetlands of piping plovers.
All work must stop immediately if a whooping crane is spotted within one mile of any project under construction.
Allow our experienced biology, natural resource, wildlife management and environmental science specialists to share our knowledge and best practices as a field survey contractor for your next project.
