That area was restricted for good reason - a nest was abandoned in that area in a previous year due to disturbance. I never enter that area betwen late march and august and don't feel it is necessary to do so as everything can be seen from the public access areas. The canal trust have been very cooperative and have chosen to impose some restriction to protect vulnerable nesting birds and I definitely think it would be a step backwards if this arrangement was undermined even by experienced naturalists. I hope you can appreciate this. Thanks
BTW: Grasshopper Warblers very often have two broods and at least one pair on site is still feeding young. They will lay second clutches in the same nest but it is possible they will use another one depending on several factors. They need to produce many young each year to maintain their numbers and Grasshopper Warblers are known to 'boom and bust' varying significantly in their numbers from year to year - about 15 years ago they went through a phase where they were a very scarce bird in Worcestershire.
must be a different nest then because this one isn't in a restricted area it is about 2 feet away from a walkway and in long grass. It has not been disturbed at all to my knowledge and i only dared step closer to it last night after sitting and observing for an hour with no sign of any movement. I know they normally have 2 broods, the same area i saw a brood scared out of a nest last year by what i assume must have been a rat or something and that was July 26th early morning. They are a great bird and its great they are breeding there now. Would you think that it is the same birds as last year that are nesting there this year?? Would like to think so.
