Check out these birds trapped in the eye of hurricane Hermine as seen on radar:

Huge bird patterns were a constant problem well into the 1970s on DEW and similar radars. Modern signal processing helps a lot.
On a side, semi-historical note, I think I first learned of the various radar lines from a relatively recent rewatch of The Deadly Mantis (1957), which has a little featurette about the systems to set up the attack on a DEW line outpost by the unfrozen prehistoric mantis of the title. The mantis only shows up intermittently on radar -- guess the systems weren't tuned for kaiju.I realize I'm replying to a necrothread, but I've only recently joined the forums. I found this thread particularly interesting because I'm interested in the history of radar and one of the earliest examples of radar UFOs were birds. They had no idea what they were and everyone concluded they were thermals, but then they went and looked and it was birds every time.
Additionally, one of the most extensive radar systems built, stretching all the way across Canada, was rendered completely useless due to birds. One of those things that was obvious in retrospect but no one was familiar with it at the time and after hundreds of millions were spend it was, well, all they have to do is attack in spring or fall and we're done.

I remember a number of years ago being wowed by a report that a single isolated radar blip was identified as a bird, and even what species of bird (a scoter) by the timing of the wingbeats.Huge bird patterns were a constant problem well into the 1970s on DEW and similar radars.
