The second eight-day period of Gullmas at Tophill Low NR, East Yorkshire continued to provide Mediterranean Gull Ichthyaetus melanocephalus, with a minimum of 10-12 individuals recorded on D reservoir between December 27th and January 3rd.
A total of 4-5 1st winter birds appeared over the period, with a single 2nd winter putting in several appearances.
Meanwhile, adults featured quite prominently with 5-6 individuals noted from photographs and field observations. Over the entire 16 day Gullmas period, a total of 12-15 birds were seen, as the breakdown below shows, while the mean roost size per night, involving all species present, was 7,600.
- 4-5 1st winters
- 2-3 2nd winters
- 6-7 adults
During the same period 12 months ago, only 4-5 individuals of this species were noted, when the roost averaged 12,590-13,990 birds per night.
Other highlights during the second period included three Yellow-legged Gulls Larus michahellis, taking the total over the Gullmas period to five – almost identical to the 12 months ago, while the strong winds from the southeast on January 3rd brought a flock of 13 Little Gull Hydrocoloeus minutus to the roost, which is (without checking the published annual reports) probably the highest, or one of the highest, winter counts in Tophill site history.
