red-winged lark (Mirafra erythroptera), grey-winged blackbird (Turdus boulboul), ashy-grey wren warbler (Prinia hodgsonii), hogson's wren warbler (Prinia cineveocapilla), lesser 
whitethroat (Sylvia curruca), crested black tit (Parus melanolophus), thick-billed flower-pecker (Dicaeum agile), willow sparrow (Passer hispaniolensis), Indian silver bill (Eodice malabarica) and spotted munia (Lonchura punctulata) were not recorded in this study whereas 11 new passerine species were identified.
However, warblers in general are struggling to maintain populations, with the 
whitethroat, once a regular summer visitor here, now seemingly absent.
But there were the usual numbers of warblers with Chiffchaff, Willow Warbler, 
Whitethroat and Blackcap all breeding in the park.
The chiffchaff, 
whitethroat and blackcap are all types of which bird?
Activists say the most common species in the traps are Blackcaps, Lesser 
Whitethroat, Garden Warblers, Nightingales, and Reed Warblers, all long distant-migrants with populations declining in most EU countries.
Among them grey heron and little egret, great black-backed gull and black-headed gull, great spotted woodpecker, blackcap and 
whitethroat, song thrush and mistle thrush, and yellowhammer and reed bunting.
The breeding bird surveys highlighted the presence of four territories from within the survey area and a further three within a 50m buffer, comprising six different species, two of which are recognised as being of national conservation concern: willow warbler and 
whitethroat. As well as the dingy skipper, the site also harbours the small heath butterfly, also of high conservation priority.
Just some of the reserve's most notable birds of interest include the goosander, "saw-billed" duck, the lapwing, snipe and 
whitethroat.
The project has already attracted 13 species of butterflies and several types of birds including blackcap, 
whitethroat and willow warbler, linnets, goldfinch, thrushes and blackbirds.

Between the woodland and the canal bridge a 
whitethroat did its stuff, and after a short while listening (and watching) I led the group, with impeccable timing, to the entrance of the wetlands.
