There would be serious implications on how useful eBird data is, because it would affect our ability to use this data for large-scale analyses of bird abundance and distribution trends like SoIB.

We decided to explore how birdwatchers in India responded to the pandemic by taking a deep-dive into the data, and comparing various metrics.
Results would tell us how useful eBird data from the pandemic years is.

# Timeline

???
"Depending on your constitution, you may feel either like the pandemic was ages ago, or as if it were just yesterday."
Greatest impact of pandemic on human activity was during the lockdown periods in both years, while other months saw highly variable impacts in different parts of the country, depending on policy, government, etc.

## Implications of changes in birder behaviour?

class: middle

Data quantity---completely unaffected

Data quality---slight changes due to birder behaviour

Species reporting---largely unaffected at large scale

Care to be taken with small-scale analyses

## eBird data still useful!
