A California woman has been dealing with a crazy bird who’s been obsessively knocking on a window of her house for a week.

Central Valley Oakhurst resident, Lupe Arechiga, can’t understand what caused the pesky bird to start knocking on the window of her home, and why it hasn’t stopped.

In a video shared by Arechiga with KMPH, the silhouette of the bird can be seen knocking on the window over and over again, apparently trying to get the homeowner’s attention.

The video goes on for more than 40 seconds with non-stop knocking.

At times in the clip, the winged creature appeared to fly into the window and start knocking. Other times the bird is perched on something outside the window and tapping on the glass repeatedly.

In a Facebook post, Arechiga said the birdbrain foul did finally stop tapping on one window, but then continued on another.

“Now she’s coming around tapping at the front window too,” she wrote on social media.  “I guess she just wants to come in.”

According to a YouTube video from the Audubon Society of Western Pennsylvania, birds tend to do this as a hormonal thing, per host Scott Detwiler.

Detwiler said it is most likely a young male bird, who he said is “attacking what he sees as a rival in the window.”

The host said the best advice he has for someone dealing with a similar situation as the Oakhurst woman is to somehow obstruct the reflection coming from the window.

He said a person can do this by using a screen in the window, but if you don’t have one of those, then he suggested using decorative spray-on snow to cut the reflection. 

And if you’re tight on funds, Detwiler said, you can always grab a candle and rub the wax on the window to obstruct the reflection.
