2008 New Jersey Preseason Duck Banding Report

Preseason duck banding operations were completed between 1 July and 30 September. Preseason banding is conducted during this period since banding locally breeding and hatched ducks is a major objective of this monitoring program.  Marking local ducks allows for the derivation of harvest or specific harvest rate analyses by geographic breeding region. The majority of preseason duck banding effort is targeted at mallards since their population status drives duck hunting regulations in North America.  In the Atlantic Flyway, Adaptive Harvest Management models for eastern mallards are currently being used to guide duck harvest management decisions.  These models are largely dependent on mallard recovery data derived from banding.

Division Waterfowl Program personnel, along with Division Wildlife Conservation Corps Volunteers, National Wildlife Refuge personnel, and other federal, state, county, and local cooperators, banded a total of 1,182 ducks.  This total included 1,024 mallards, 32 American black ducks, 2 mallard X black duck hybrids, and 124 wood ducks.  An additional 103 previously banded ducks were recaptured of which 99 were mallards.  Although over 35 banding stations were active, ducks were banded at 26 locations in 13 counties from Warren and Bergen in the north, to Cape May and Cumberland in the south.

This was the sixth consecutive year where over 1,000 mallards were banded. The preliminary mallard immature to adult ratio during banding was 0.872 and was above the long-term mean of 0.639.  Since 1993, the mallard immature to adult ratio during banding has ranged from 0.287 (2002) to 1.138 (2007).

The Division collaborated with USDA-Wildlife Services and Forsythe NWR to conduct a surveillance program for Highly Pathogenic Avian Influenza (HPAI) Type H5N1 during preseason banding operations. The Division sampled 118 mallards, 40 wood ducks, and 13 black ducks at 14 sites in 9 counties from Cape May to Middlesex. Complete laboratory results have not yet been received.  To date, HPAI H5N1 has not been detected anywhere in North America.  Sample collection will continue this fall and winter with additional species of shorebirds and waterfowl.
