  Great Reed Warbler - Wikipedia, the free encyclopedia
The Great Reed Warbler, Acrocephalus arundinaceus, is an Old World warbler in the genus Acrocephalus.
3-6 eggs are laid in a basket nest in reeds.
This is a large Song Thrush-sized warbler, 16-20cm in length.

 Clamorous Reed Warbler - Wikipedia, the free encyclopedia
Clamorous Reed Warbler is a large Song Thrush-sized warbler at 18-20 cm.
It is very like Great Reed Warbler, but that species has richer coloured underparts.
Like most warblers, Clamorous Reed Warbler is insectivorous, but will take other small prey items.

 Birds of reed vegetation: shrubs and trees are encroaching marshland - Environmental Data Compendium
The birds of reed vegetation have declined because reed vegetation is dwindling.
The reed fringes of open water are becoming narrower, because the water quality is poor and the water level no longer fluctuates naturally (high in the winter and low in the summer).
Furthermore, reed is being ousted by shrubs and trees, a process reinforced by the repercussions of water draw-down and by the eutrophication of the surface water.

foreign forms of aquatic warblers are far too numerous to be here mentioned.
The Australian genus Malurus, to which belong the birds known as " superb warblers," not inaptly so named, since in beauty they surpass any others of their presumed allies, is now placed in with the Old World fly-catchers in the family Musicapidae.

We tested the importance of nest cleaning in egg rejection behaviour of the great reed warbler Acrocephalus arundinaceus in a highly parasitised population in which about 64% of nests are parasitised by the common cuckoo Cuculus canorus.
Three types of objects of the same weight, texture and colour but with different shapes (dummy cuckoo eggs, sticks and disks) were placed into great reed warbler nests.
We investigated the response of hosts in two stages of breeding: pre-incubation when the risk of brood parasitism is high, and during incubation when the risk of parasitism is low.

 Ecology: Patterns Of Nest Predation Contribute To Polygyny In The Great Reed Warbler   (Site not responding. Last check: 2007-11-07)
In the polygynous Great Reed Warbler (Acrocephalus arundinaceus), the variation in territory quality may be associated with nest site characteristics or food supply.
Artificial nests with attached soft plasticine model eggs were placed in Great Reed Warbler territories of different attractiveness, Marks in the soft model eggs were compared to marks from possible predator species.
We found that in Great Reed Warblers the rate of nest predation was lowest in territories of high attractiveness (inhabited by polygynous males) and highest in territories of low attractiveness (inhabited by monogamous and unmated males).

In the breeding season, male great reed warblers use regular song perches.
Often, though, these are low down in the reeds, which makes it difficult to photograph the songsters.
It was early morning when this male perched on a high stem close to me. For a few moments, he was bathed in a golden light, and I could see the breath of his song notes rise up in the cool morning air.

The risk of cuckoo (Cuculus canorus) parasitism for great reed warbler (Acrocephalus arundinceus) nests was evaluated in respect to nest and nest site structure in the reedbeds along canals in central Hungary.
Besides the robust effects of the variables "distance to cuckoo perch site" and "nest visibility", the variable "distance from nest to open water" may reduce, but "nest volume" increases the risk of multiple parasitism.
There was no evidence that great reed warblers nested closer to each other when risk of parasitism was high.

I am studying MHC genes in a population of wild songbirds, great reed warblers Acrocephalus arundinaceus.
In order to be able to study MHC class I diversity in the great reed warblers I developed a PCR-based screening method.
I found a large number of MHC loci and also a surprisingly high level of allelic variation in the great reed warblers, in contrast to the limited variation that was detected using neutral markers.

 Acrocephalus scirpaceus
The Reed Warbler can be found almost exclusively in reedbeds during the breeding season.
The Reed Warbler lacks the broader tails and clearer eyestripes of Savi's and Cetti's Warblers and the impressive size of a Great Reed Warbler.
This leaves Marsh and Blyth's Reed Warbler which are exceptionally difficult to separate from Reed Warbler but far less likely to be seen in reedbeds.

 BIRDTRIP Archives -- June 1997, week 2 (#3)
In the marsh itself the "karre...karre..keet" of the Great Reed Warbler and the explosive song snatches of the Cetti`s Warbler Cettia cetti absolutely dominated.
The Great Reed Warbler were easy to watch as they sang and postured in last year`s dead Phragmites stalks, while the Cetti`s warbler, as usual, mostly was "a voice in the marsh" and usually only allowed glimpses of its rusty brown body and full round tail.
The Reed Warbler Acrocephalus scirpaceus (In Holland the Small Karekiet, while arundinaceus is the Great Karekiet!) was also common, but less so, and at first sight now somewhat concentrated to the areas that had not been burned last winter and that therefore had taller old reed stalks.
