Anybody else noticed how the increase in the number of Indian mynah birds corresponds with the reduction in the number of sparrows and other smaller birds?

Indian Mynahs are voracious invaders of the nests of other birds and they are also oviraptors.
Perhaps there are less sparrows etc because of this.

Sparrows are not nice but these grubby things? every coastal town and many a bit further away in NSW is suffering.
Even some green groups are killing them.
I started a bird friendly garden in 2002 now its a haven but my Finch's living in great bottle bush trees have been killed by these pests.
Feathers? oh nothing to be concerned about ,bit of a virus, strange it only kills one type of bird.
Still a few thousand around if you look.

Townsville is full of both mynahs and sparrows. There are also many other small birds that nest in urban areas, such as sunbirds, mistletoebirds, brown honeyeaters, etc, as well as several slightly larger mynah-sized species.

Mynahs don’t appear to influence sparrow numbers. And neither do sparrows nor mynahs seem to influence the abundance of other birds.

It is interesting to note that mynahs are abundant in the intensive agricultural areas of the lower Herbert and in the urban area of Ingham but are absent from the almost identical sugarcane-dominated lower Burdekin area and the urban areas of Ayr and Home Hill.

I am a pretty full-on birdo. I’ve done many trips around the lower Herbert and Burdekin areas and I haven’t noticed the slightest bit of difference in native species composition or abundance. So I can pretty confidently say that mynahs don’t significantly affect native birds.
