Please see below a summary for nest boxes installed within the Selly Oak and Hall Green wards:


SITE NAME: RSPB WOODLAND - CANNON HILL PARK
BOXES INSTALLED:10

BOXES OCCUPIED: 1

SPECIES: Blue Tit

BOX OUTCOME: Box failure - deserted at egg stage
I was surprised about the number of unoccupied boxes within the above sites and especially for the RSPB Woodland at Cannon Hill. It is possible that increased competition for natural nest sites in the better quality habitats (mature broad leaved woodland) results in the birds prospecting earlier in the year and given the boxes were installed relatively late (February) the hole nesting birds may have already scoped out potential nest sites before the snow arrived.

However, the plan is to monitor the boxes for the next two years so the story is far from complete and it is hoped the mist netting exercise will shed more light on general bird density, species diversity and bird turnover rates at each of the study sites.

Brockley Grove - then and now

Holders Woods and Fields east of centre with Brockley Grove to the south, road and turning circle Article from Birmingham Forum website -  My old mum and I moved into a prefab on Brockley grove just off dog pool lane (dads lane) in moseley in about 1959 and my old mum thought it was heaven, it had a "fitted kitchen" i.e a built in washing machine, she'd always had to do her washing by hand before and in both bedrooms were "metal" fitted wardrobes. As it was detached, standing surounded with a nice little garden we both loved it. unfortunatly it' now been demolished and  Brockley grove is now unsign posted and is a dog walking area but I will always have very fond memories of mom's little "bungalow". This map shows the layout of the Brockley Grove prefabs

Lifford - William Dargue - A History of BIRMINGHAM Places & Placenames

Lifford Woods An area of land bordering the River Rea at Allens Croft, with a pathway to Lifford Reservoir and Lifford Hall. The linear woodland runs either side of the river with willows and alders thriving. The site is little used today, with most people passing along the walkway, whilst much of the area is out of the public domain, cut off by railway embankment and the river.  In terms of wildlife, I guess this is under recorded, as are most sites, all records should be submitted to EcoRecord and twitter is a good way of doing this.  Lifford Woods and surrounds The account below is taken from "Lifford - William Dargue - A History of BIRMINGHAM Places & Placenames" B30 - Grid reference SP055796 la Ford: first record 1250 Lifford stands close to the ford across the River Rea. As the red clay on the east side of Birmingham became slimy and slippery in wet weather, a place where the river ran over a firmer bed would have been a draw ...

New Trees - Woodland Wednesdays at Highbury

Highbury Park and neighbours - wooded Wooded Highbury The term 'replete' has recently been used in reference to the wildlife provision at Highbury, and whilst the park can boast a healthy list of trees and bird life and perhaps reasonable opportunity for invertebrates, there is certainly room for enhancement and improvement in this regard. The park is jealously viewed and guarded by its regular visitors and protest quickly develops as changes occur - for example recently planted hedges were met with anxiety and vandalism, new desire lines are seen as trespass and the recently announced proposal to improve the tarmac surfacing for cyclists was greeted with the following- https://www.birminghambeheard.org.uk/place/bcr3-highbury-park-walking-and-cycling-route Consultation  Politics aside, if that's possible, an overview of the wooded fabric of the park would probably indicate a net loss of timber over the past 5 years due to ageing, and the need to 'mak...
