觀察細節
Lemon-scented Gumtree. Subject Male on P1a facing 330° NW. Female on P1b facing 16° N. Male Interloper facing 88° E The Male Interloper was active and aware of its surrounds from around 5.26pm. The Subject Male and female started to be aware from 5.30pm. At 5.33pm the Subject Male was staring intently down at the Male Interloper which was in turn staring up at the Subject Male bird. At 5.36 the Subject Male flew off its perch down onto another perch but still slightly above and around 2.5 metres from the Male Interloper. The Male Interloper was trembling and slightly opening and closing its beak repeatedly. At 5.39pm the Subject Male attacked the Male Interloper knocking it off its perch causing the Male Interloper to emit a rasping, croaky call and landing in the Jacaranda tree approximately 6 metres to the east of the Lemon-scented Gumtree. At 5.41pm the Subject Male launched another attack with both birds ending up in the Jacaranda tree approximately 1.5 metres apart and the Subject Male's position slightly lower than the Male Interloper's position. The female bird began preening and stretching at 5.55pm and at 5.56pm moved from P1b to P1a and stretched again at 5.59pm. At 6.06pm the female bird was watching the Male Interloper intently, opening its beak at the other bird. The female was switching its gaze between the Male Interloper and the Subject Male before flying off at 6.12pm 17 minutes after it started preening and stretching in a direction of 24° N landing in the bare Mountain Ash Tree on the northern side of the north boundary. The Male Interloper followed approximately 15 seconds after the female bird heading past and to the right of the female's position. The Subject Male was still on the same perch in the Jacaranda tree after the second attack at the end of the survey. There were several Grey-headed Flying Foxes about and no sightings of any domestic animals.
