Some of the UFOs are just illusions, see the video above.
True, the birds argument is convincing enough for me, but what's more interesting is why they created the hype? What's the agenda or is it a mere coincidence? I think the question is worth asking 
Nowadays, media is trying to cope up with the news circulating around the social media especially if they are getting the hype. This medias are still a corporation that needs funding and incomes, and for them to gather incomes, they need viewers in which most probably are very interested in these kind of things. The news about other essential topics such as Covid is still being discussed in those channel, but for new news that will pique the interest of the viewers, they need to covers this such things.
Also, even though they are being covered in by known media, that doesn't mean that those people are believing in this things, I think they debunked it at some point in those news.
