Explanation:

The Great Backyard Bird Count (GBBC) is an event to create a real-time snapshot of bird populations. Participants are asked to count birds for as little as 15 minutes (or as long as they wish) on one or more days of the four-day event and report their sightings online at birdcount. Anyone can take part in the Great Backyard Bird Count, from beginning bird watchers to experts. One can participate from his/her backyard, or anywhere in the world. Each checklist submitted during the GBBC helps researchers at the Cornell Lab of Ornithology and the National Audubon Society learn more about how birds are distributed across the country and how they are affected by changes in habitat and weather.

Statement 1 is incorrect: Indian birders have participated in the GBBC since 2013. In India, GBBC is coordinated by the Bird Count India (BCI) collective, a coming-together of a number of groups and organisations that are interested in birds, nature and conservation.

Statement 2 is correct: India contributed 22,273 lists, the second highest after the U.S. Tamil Nadu's Salem district submitted the largest number of checklists, at 8,420, among all participating districts to the global Great Backyard Bird Count 2019.
