Breeding Bird Classification System
Rules and Guidelines for Breeding Bird Surveys Adopted May 2000
Data is collected and analyzed using a modified protocol fashioned from regulations established by the National Audubon Society and the Cornell Laboratory of Ornithology for bird censusing. The created methodology used for collection of data is very similar to the one developed for the Saw Mill Creek Breeding Bird Surveys from 1992-1994 (Aquila, 1995). It is a composite methodology that relies heavily on two sources of breeding bird standards. It incorporates the classification system developed by the Federation of New York State Bird Clubs (Federation of New York State Bird Clubs, 2000) and the mapping system developed by the National Audubon Society (Robbins, 1970). Our system fuses the two systems together in this way: any “mapped territory” as defined under the Audubon system constitutes a “Confirmed Breeding” status under the New York State Federation of Bird Clubs classification system.
A Spring Breeding Bird survey consists of eight separate visits to the site between the dates of May 15 and June 30. Previous surveys performed by NRG have begun in the morning hours between 4:30 AM and 7:30 AM, and finished between 12:00 NOON and 2:15 PM. Since many of the birds are located by their singing/calling, the surveys began early, when many of the birds reach their peak vocal activity, roughly, 30 minutes after sunrise (Ralph, et. al, 1993). Using the National Audubon Society’s methods for mapping in bird census work, we map each observation. When located, either by sight or sound, each bird is plotted on a map; preferably at 1”=200’ scale. The map should consists of an aerial photographic base and a symbol layer. Each species of bird is given a preset abbreviation that was marked on the map. Another symbol is then given, indicating the behavior or movement of the individual bird. This system is instrumental in determining the breeding status of birds and in marking individual territories. Recording bird behavior is also helpful in distinguishing the non-breeders or “flybys” from those birds that were utilizing the marsh for a reason related to their breeding status.
According to our classification system from the methods provided by the New York State Federation of Bird Clubs and the National Audubon Society system, bird behavior is categorized under three classes: “Confirmed”, “Probable” and “Possible”. To confirm the breeding of an individual bird in Saw Mill Creek Preserve, any of the following specified conditions had to be met:
1. Observing territorial behavior of the bird on consecutive dates towards humans and other birds upon approaching territory, or vocalization from locations around the perimeter of its territory three (3) or more consecutive dates.
2. Two (2) or more of the consecutive sightings must occur in the month of June.
3. Discovery of an active nest, eggs, or observation of a bird carrying food or a fecal sac, or, in the case of most bird species, carrying nesting material automatically confirms the bird as a breeder without having to meet the above requirements.
For an individual bird to be listed as possessing “Probable” status, it had to meet any of the following conditions:
1. Observation of a singing male on more than one (1) date in the same place.
2. Observation of a pair of the same species during the breeding period suitable for the given species.
3. Observation of territorial behavior displayed by a single bird or a pair of the same species.
4. Observation of courtship or display, agitated or anxious behavior.
5. Observation of nest building (does not apply for all species).
For an individual bird to be listed as possessing “Possible” status, it had to meet the following condition:
1. Observation of a species in a possible nesting habitat, but having no other indications of breeding.
Birds seen that do not possess any category of breeding status are listed under a different set of conditions, which were created for this survey. Birds listed under these categories may have or may have not met any of the conditions listed above. The categories considered include “Non-breeding”, “Locally Breeding”, and “Migrant”.
For an individual bird to be listed as “Non-breeding”, they have to meet the following conditions:
1. Observation of a species that is not known to breed in the region (Arthur Kill Waterway complex).
2. The individual did not indicate any signs of being a migrant (see below).
3. The individual did not meet any of the conditions to be considered for breeding status.
4. The individual demonstrated the capacity to linger in the area. (ex.- juvenile or injured bird)
For an individual bird to be listed as “Locally Breeding”, it has to meet the following conditions:
1. Observation of a species that has been known to breed in the region (Arthur Kill Waterway complex).
2. The individual did not meet the conditions of a “Confirmed” breeding bird species.
For an individual to be listed as “Migrant”, it has to meet the following conditions:
1. Observation of a species that is known to have a migration pattern through the area during the given time period.
2. The individual exhibited characteristics of a migrating bird.
3. The individual bird demonstrated the capacity to leave the region via migration.
