Does anyone know if this is a mating thing? These 2 weeks my male lovebird started to produce this one high pitch that resembles the carbon monoxide detector. Not that he heard one learned from it but he just invented it by himself and make this sound a few times every hour. I hope this is not a forever thing... kinda annoying ;P And that one pitch is quick, it's even hard to tell that it came from him but we just know... well i expect my female lovebird to lay some eggs soon and we'll see if their behavior changes after... I'll give them dummy eggs to replace the real ones
