Keith, it puzzled me too. I think he is saying that in urban Digbeth he reached a score of somewhere between 10 and 20 different species. I haven't been able to make the web-link work to check if that is right.

John told me of your donation. Thanks.
Paul
He called in today and 2 followed him
Thanks Peter...It's b***** obvious now you have told me....lol
Worked in Digbeth for 27 years....one highlight was the Black Redstarts...before I lost my ability to hear most birds singing the Males were spectacular singing out over the traffic.
Keith :t:
Stunning! Well done. I have just joined the ranks of the macro mob. Looking forward to beginning to practice...hi all,just one photo from a different world,next time you walk pass the gate to the east hide take a look on top of the one post Mary did.
Very sorry for the confusing post. Yes, I saw around 15 species in urban Digbeth on Sunday morning. The link that apparently didn't work referred to urban birding in London (where diversity is increasing), and Parakeets are common to the west of London.
Apologies again for the confusion.
This concern has been raised regarding the South Birmingham pair but so far the parakeets have had no affect on other tree hole nesting birds.
At another, earlier location in South Birmingham, ring necked parakeets stayed around for about three years. During this period lesser spotted woodpeckers successfully bred in a tree adjacent to where the parakeets nested.
It is thought the demise of the original pair was caused by sparrowhawk predation.
Blackredstarts
Now gone from those parts it seems. Used to breed by the Blues ground.
The purpose of the 2004 Eastside/Digbeth survey was to identify black redstart breeding territories so any subsequent development wouldn't adversely affect these birds. One idea was to promote the use of green roofs.
The resident population was overestimated. At best there were no more than two breeding pairs. There were several non breeding males which might have caused some confusion. Historical records had also been added which inflated the number.
As said earlier, I recorded nearly forty species of bird over a three month period. Approximately three quarters were breeding or probable breeding. However, at least a third were declining and are now probably absent:
grey heron, canada goose, mallard, sparrowhawk, kestrel, peregrine falcon. moorhen, coot, lesser black backed gull, wood pigeon, collared dove,swift, swallow, grey wagtail, pied wagtail. wren, dunnock, robin, black restart, northern wheatear, blackbird, song thrush, mistle thrush, common whitethroat, blackcap. chiffchaff, willow warbler, blue tit, great tit, magpie, carrion crow, starling, house sparrow, chaffinch, goldfinch, linnet.
The point I was making was ring necked parakeets don't affect smaller hole nesting birds such as lesser spots or nuthatches.
Can someone explain to me how they think Ring-necked Patakeets - a secondary cavity nester -could interfere with the nesting prospects of Nuthatch or Lesser Spotted Woodpecker? Bit of a size mis-match don't you think? Surely they would compete with larger species for nesting sites - such as Stock Doves and Little Owls.
Point taken, Dave. You are quite right. I just grabbed the first tree-nesting bird I could think of as an example.
