believe it - or not

When I read the article, I doubted that the scientists were able to see the differences between the two species of woodpeckers when the woodpecker is only visible for one or two seconds – and 20 m away. But I am not an ornithologist. And the video is much better than I expected it (b/c the pictures are very fuzzy), and now I can imagine that this could be enough for specialists. What partly convinced me are the comparisons made in Fig. 2 and the rejection of a "piebald"/leucistic pileated woodpecker as a result of long observations in the area where the ivory- billed woodpecker (?) was seen. However, there are still doubts. I want to believe that this species exists but do not know if I can.
