  • The influence of colour-rings on recovery rates of Herring and Lesser Black-backed Gulls

    C. B. Shedden, P. Monaghan, K. Ensor and N. B. Metcalfe Ringing and Migration. (1985) 6: 52-54.

    Comparison of recovery rates of Herring and Lesser Black-backed Gulls with and without colour-rings in addition to a metal ring shows that colour- ringed birds are twice as likely to be recovered and reported to the British Trust for Ornithology. Implications for studies of mortality rates are discussed.

    Martin Gottschling Der Falke 51, 148-155

    Yellow-legged Gull Larus michahelllis and Caspian Gull Larus cachinnans are not found in many standard field guides. Only in recent times have these been recognized as separate species, which decades ago were still counted as Herring Gull. Hints and tips for the determination of the two very similar species are important for birdwatchers.

  • Scandinavian Herring Gulls wintering in Britain

    Coulson, J. C., Monaghan, P., Butterfield, J. E. L., Duncan, N., Ensor, K., Shedden, C. and Thomas, C. Ornis Scand. 15: 79-88.

    Biometric information was obtained from 13000 Herring Gulls Larus argentatus caught and ringed in northern England and southern Scotland outside the breeding season between 1978 and 1983. Morphological differences between males and females and between British and Scandinavian Herring Gulls have been used to identify both the sex and race of the birds. We describe the wintering distribution of the Scandinavian birds in Britain, their age and sex ratios and their time of arrival in and departure from Britain. Scandinavian Herring Gulls start to arrive in Britain in small numbers in September. The proportion of Scandinavian birds increases to a peak in December- January and the birds depart abruptly in late January or early February. Very few Scandinavian Gulls penetrate to the west side of Britain, while on the east side there is considerable regional variation in the proportion of Scandinavian birds. Between 70% and 80% of the adult Scandinavian birds examined were female. The proportion of adults amongst Scandinavian birds was much higher than amongst British birds.
