| Three poachers were caught red-handed trying to lure watercocks and yellow bitterns by using a recording of a bird's mating call here yesterday. |
|
| He reported that bitterns were beginning to practise their boom on the reserve again but would not find their full voice until April or May. |
|
| And Doncaster will hopefully soon be ringing with the boom of bitterns crying out for mates. |
|
| The date of the first booming bitterns varies each year, although there has been a trend towards them starting to boom earlier in recent years. |
|
| Leighton Moss, a premier RSPB reserve where you can hear bitterns boom, is a lovely walk away over the crag. |
|
| The photo below was taken in attempts to show the powder down feathers which outline the furcular hollow and are unique to herons and bitterns. |
|
| Volunteers at Marbury Country Park, near Northwich, spotted three booming bitterns, members of the heron and stork family, feeding among reedbeds. |
|
| By listening to the booms and looking at their spectrograms, the scientists can distinguish between individual bitterns and count them more accurately. |
|
| It doesn't take much to get him on to the subject of the nightingales, otters, barn owls and even notoriously shy bitterns now living alongside the humans at Lower Mill. |
|
| I've heard Bitterns booming a few times at Leighton Moss, but I can only imagine what Minsmere sounds like on a spring evening. |
|
| Bitterns are one of the UK's rarest birds, with only 30 breeding pairs left as marshland habitats dry out. |
|
| Bitterns are virtually invisible as their plumage provides perfect camouflage. |
|
| The grey heron was anyway considered to be the best of a group of birds with similar lifestyles, to wit other herons and night herons, egrets, bitterns, and cormorants. |
|
| For many years male bitterns have been considered at times bigamists. |
|
| The trees and shrubs attract thousands of migrant dickey birds, and the marsh vegetation attracts several species or rails, American Bitterns, and Black-crowned Nightherons. |
|
| This is characteristic of herons and bitterns, and distinguishes them from storks, cranes, and spoonbills, which extend their necks. |
|
| The survey work will focus on species such as Virginia and Sora rails, least and American bitterns, and marsh wren. |
|
| Starting then and for the rest of his life, he photographed bitterns, red-winged blackbirds, and marsh wrens, among other bird species. |
|
| I was lucky enough to visit Minsmere and Dunwich Heath last week and there seemed to be Bitterns booming everywhere, although I didn't actually see one. |
|
| Ibises, spoonbills, herons and the desolate bitterns have been classified in the same order. |
|
|
|
| These included herons, egrets, and bitterns, ibises, storks, and Limpkin. |
|
| But once upon a time, bitterns nested in every pothole marsh and every streamside cattail patch from British Columbia to Newfoundland and from Florida to California. |
