Answer:
The difference between the Big Year and the Great Backyard Bird Count is related to the purpose of each activity, one related to each person's ability for sighting birds and the other to people's contirbution to science by watching birds at home.
Explanation:
On the one hand, Big Year is about breaking the record of who sees more different kinds of birds in one year. As Kowalsky states, participants on the Big Year are motivated to achieve this because of their love of birds, bonding with others who share the same interest, and travelling. This is related to why they keep honest in their bird count as according to the article “No pictures or other evidence is required as proof of a sighting. Most birders take great pride in their reputation and their abilities to see or hear and then identify a bird”.
On the other, the Great Backyard Bird Count is about participants’ contribution to scientific knowledge about bird populations. According to the “Extra! Extra!” section, people who are interested on birds are invited by scientists to watch the birds that they see in the places they frequent and to record their sightings on a website. This data then is used to understand how bird populations are doing.
