-The route-regression method has been used in recent years to analyze data from roadside surveys. With this method, a population tr~nd is estimated for each route in a region, then regional trends are estimated as a weighted mean of the individual route trends. This method can accurately incorporate data that is unbalanced by changes in years surveyed and observer differences. We suggest that route-regression methodology is most efficient in the estimation oflong-term (>5 year) trends, and… 
The Importance of Analysis Method for Breeding Bird Survey Population Trend Estimates
Population trends from the Breeding Bird Survey are widely used to focus conservation efforts on species thought to be in decline and to test preliminary hypotheses regarding the causes of these
ESTIMATING POPULATION TRENDS WITH A LINEAR MODEL
Abstract We describe a simple and robust method for estimating trends in population size. The method may be used with Breeding Bird Survey data, aerial surveys, point counts, or any other program of
New Approaches to the Analysis of Population Trends in Land Birds
TLDR
Using pooled data for all 26 species for eastern and central North America, nonlinear regression indicated declining populations in the Appalachian Mountains and the Eastern Foothills in the 1970s, and stability elsewhere, suggesting that correlates of elevation should be considered as factors possibly regulating populations of warblers and other land birds.
Combining Breeding Bird Survey and Christmas Bird Count Data to Evaluate Seasonal Components of Population Change in Northern Bobwhite
Abstract Annual surveys of wildlife populations provide information about annual rates of change in populations but provide no information about when such changes occur. However, by combining data
Analysis of monitoring data with many missing values: which method?
Large-scale monitoring of bird species becomes more and more important in many countries. In the datasets yielded by these censuses, values are often missing. This poses problems in the analysis of
A HIERARCHICAL ANALYSIS OF POPULATION CHANGE WITH APPLICATION TO CERULEAN WARBLERS
Estimation of population change from count surveys is complicated by variation in quality of information among sample units, by the need for covariates to accommodate factors that influence
ANALYSIS OF MONITORING DATA WITH MANY MISSING VALVES: WlllCH METHOD?
Large-scale monitoring of bird species becomes more and more important in many countries. In the datasets yielded by these censuses, values are often missing. This poses problems in the analysis of
Accounting for Surveyor Effort in Large-Scale Monitoring Programs
Accounting for errors in wildlife surveys is necessary for reliable status assessments and quantification of uncertainty in estimates of population size. We apply a hierarchical log-linear Poisson
Estimating statistical power to evaluate ongoing waterfowl population monitoring
TLDR
Retrospective power analysis is applied to evaluate both population trends and survey design in the waterfowl surveys conducted by the Canadian Wildlife Service and others around Riske Creek, British Columbia to support the conclusion that little change occurred.
Generalized linear models and point count data: statistical considerations for the design and analysis of monitoring studies
The success of avian monitoring programs to effectively guide management decisions requires that studies be efficiently designed and data be properly analyzed. A complicating factor is that point

TLDR
It was concluded that the chick index presented here cannot generally be used as a population indicator because of an absence of correlation in 30 species.

TLDR

Counts of birds are used for many purposes in a variety of field studies. Simple presence-or-absence information suffices to study avian biogeography, but indices of abundance are needed to track the
Efficiency of Two Methods for Monitoring Bird Population Levels: Breeding Bird Censuses Contra Counts of Migrating Birds
TLDR
In terms of costs a population monitoring programme based on breeding bird counts will be considerably more efficient in detecting trends than a programme using trapping totals, and it is supposed that the high variation in the migration counts is caused by weather factors.
