B. Collection of Information Employing Statistical Methods


The agency should be prepared to justify its decision not to use statistical methods in any case where such methods might reduce burden or improve accuracy of results. When Item 17 on the OMB Form 83-I is checked “Yes,” the following documentation should be included in the Supporting Statement to the extent that it applies to the methods proposed.


1. Describe (including a numerical estimate) the potential respondent universe and any sampling or other respondent selection method to be used. Data on the number of entities (e.g., establishments, State and local government units, households, or persons) in the universe covered by the collection and in the corresponding sample are to be provided in tabular form for the universe as a whole and for each of the strata in the proposed sample. Indicate expected response rates for the collection as a whole. If the collection had been conducted previously, include the actual response rate achieved during the last collection.


Statistical methods are not used in the selection of respondents. Qualified participants (i.e. individuals with the ability to identify all birds in an area by sight and vocalizations) are found via word-of-mouth and limited advertising. In 2016, for example, 1,912 individuals volunteered to participate and 1,603 of those individuals responded. They collected avian population data from 2,614 U.S. BBS routes.


2. Describe the procedures for the collection of information including:

* Statistical methodology for stratification and sample selection,

* Estimation procedure,

* Degree of accuracy needed for the purpose described in the justification,

* Unusual problems requiring specialized sampling procedures, and

* Any use of periodic (less frequent than annual) data collection cycles to reduce burden.


Routes are established in each State using a stratified random design where degree blocks form the basic stratification unit. Within each degree block, route start locations and direction of travel are randomly chosen. Survey participants are not randomly chosen; only individuals skilled at vocal and aural bird identification may participate.


Fifty 3-minute point counts are conducted along each Breeding Bird Survey route. All birds seen within a 0.25-mile radius and all birds heard are identified as to species and counted. These counts provide an index of abundance that represents a portion of the individuals present at each stop. These indices are then analyzed to derive population trend estimates. Trend estimates are calculated using a Bayesian hierarchical model analytical procedure (Sauer, J.R. and W.A. Link. 2011. Analysis of the North American Breeding Bird Survey using Hierarchical Models. The Auk 128: 87-98.)


There can be substantial variation in the identification and counting skills of BBS participants. Observer bias is controlled for by using observers as co-variables within the analyses (Peterjohn, B.G., J.R. Sauer, and C.S. Robbins. 1995. Population trends from the North American Breeding Bird Survey. 1995. Pp. 3-39, in Ecology and Management of Neotropical Birds. Oxford University Press, Inc.).


3. Describe methods to maximize response rates and to deal with issues of non-response. The accuracy and reliability of information collected must be shown to be adequate for intended uses. For collections based on sampling, a special justification must be provided for any collection that will not yield "reliable" data that can be generalized to the universe studied.


Respondents voluntarily decide to participate and report; response rates remain relatively constant between years in the short run. Participation has increased over the last 50 years and regional population estimates are weighted by route density.


4. Describe any tests of procedures or methods to be undertaken. Testing is encouraged as an effective means of refining collections of information to minimize burden and improve utility. Tests must be approved if they call for answers to identical questions from 10 or more respondents. A proposed test or set of tests may be submitted for approval separately or in combination with the main collection of information.


All new participants in the BBS are required to complete a BBS Methodology training program and successfully complete a 20-question review to help insure consistency in data collection practices. The 20 questions are randomly chosen from a set of 33 possible questions. The questions are attached (BBS Methodology Training Review Questions). There are four sections to the review. Five questions are asked in each section. The review is pass or fail. Participant may re-take review as necessary. Each new participant is required to pass the review prior to participating. The training and review takes approximately 30 minutes to complete. Approximately 140 participants complete the training and review each year.


  1. Provide the name and telephone number of individuals consulted on statistical aspects of the design and the name of the agency unit, contractor(s), grantee(s), or other person(s) who will actually collect and/or analyze the information for the agency.

BBS Methodology Training Review Questions:

T/F

The North American Breeding Bird Survey (BBS) is coordinated jointly by the USGS Patuxent Wildlife Research Center and the Canadian Wildlife Service.

MC

Which of the following are requirements for participation in the BBS? Choose all that apply.

MC

At what time of day should a BBS route begin?

T/F

BBS routes should be sampled once per year, primarily in June for most of the U.S. and Canada.

T/F

BBS routes may be conducted during heavy rains.

MC

How many point count stops comprise a Breeding Bird Survey route?

T/F

Ideally, point count stop locations should be spaced at 0.25-mile (400-m) intervals.

MC

When conducting a BBS route, when should weather conditions be recorded? Pick all that apply and then click submit.

MC

The North American Breeding Bird Survey began in what year?

MC

How long should a BBS point count last at each stop?

T/F

The observer should count all birds seen within a 0.25-mile radius of the point, except dependent young and adults known or strongly suspected to have been recorded at a previous stop.

T/F

The observer should count all birds heard regardless of distance, unless known or strongly suspected to have been recorded at a previous stop.

MC

An assistant may not help the observer with which one of the following BBS activities?

MC

Which methods of attracting birds are allowed while participating in the BBS?

T/F

Flocks too large to be counted during the allowed time period should be estimated.

T/F

Written documentation should be supplied for any rare or unusual species detected on a route.

T/F

There is no need for a BBS participant to scout the route prior to conducting the survey.

T/F

Stop locations may be moved up to a 0.1 mile (160 m), forward or back, to avoid an unsafe stop location.
