The timing of the arrival and departure of migratory birds is largely impacted by temperatures, therefore, changes in climate can lead to shifts in migratory bird patterns and lead to novel impacts of asycronicity.
There are 5 protocols that are used to monitor the indicator: Changes in Arrival Date. The first three studies on the list below are the most common methods of monitoring in the Northeast region.
The impacts of climate indicators can be measured using different ecological metrics of quantification. The metrics used in a study can affect how it is designed and the questions that it can answer. The information below shows the types of metrics and number of associated protocols that are captured by the data represented in this project.
