TRAVELLING NATURALIST TRIP REPORT
12 - 19 May 2001
PROGRAM AND WEATHER
Saturday 12 May. Light wind, sunny.
We all arrived in good time at Penzance Heliport on a glorious day for our flight to the Scillies. Unfortunately our late afternoon flight was significantly delayed and we eventually arrived at our respective guesthouses early evening. As usual we attended Will Wagstaff's slide show in the evening, an excellent introduction to the natural history of the islands.
Sunday 13 May. Light wind, sunny.
Fine weather enabled us to enjoy our traditional 'Seabird Special' cruise. We sailed around the coasts of Samson and Tresco looking for waders and terns before venturing out into more open water and looking for seabirds around Round Island and Men-a-vaur. The afternoon was spent exploring Tresco.
Monday 14 May. Light southerly becoming northeasterly wind. Max temp: 14C.
During our pre-breakfast walk to Peninnis Head we successfully found the two and only Rooks on the islands.
The day was spent exploring the paths and nature trails of St Mary's. Although migrants were few and far between we all enjoy seeing the fine displays of flora which are a feature of Spring on the Scillies.
The evening 'Shearwater Cruise' took place on a warm, fine evening and we all enjoyed close views of the shearwaters as they waited offshore before returning to their burrows at night.
Tuesday 15 May. Light northeasterly becoming southeasterly wind. Max temp: 13C.
We returned to Tresco for a more leisurely look around. The highlight of the day was a fine Spoonbill quietly resting alongside the Great Pool. This is the first year that Pochard have bred on the Scillies and we saw 2 pairs and a female with 1 duckling. An interesting scattering of migrant waders included Little Ringed Plover, Common Sandpiper and Greenshank.
The sunshine turned to rain in the afternoon but we were still able to admire the spectacular plants in the famous Tresco Abbey Gardens.
Wednesday 16 May. Fresh southwesterly wind. Max temp PS:14C.
On arriving on St Agnes we heard the news that a Cattle Egret had arrived on the island, the first ever on Scilly. After taking a leisurely walk around the coast we eventually had distant views of this bird being mobbed by gulls. After a very picturesque lunch stop in glorious weather we headed out onto the exposed southern part of the island. Heavy showers suddenly arrived and we made good use of the mainly large granite boulders to shelter from the inclement weather.
The day was spent on Bryher where as usual one of the highlights was seeing the diminutive Dwarf Pansies in what is probably their only British sight. Studying the flowers through the telescope avoided the inevitable 'bottoms in the air' pose normally associated with looking at tiny flowers.
Saturday 19 May.
Thankfully, fine weather enabled us to leave the island on our scheduled early morning flight.
Great Northern Diver: 4 seen during the 'Shearwater Cruise', 2 of which were alongside the boat.

Jackdaw: We saw 4 on Tresco on 13th and 2 on 15th, 1 on St Agnes on 16th and 1 on Bryher on 18th. These sightings probably account for all the Jackdaws on the islands.

I thank Will Wagstaff for his excellent leadership and sharing his wealth of knowledge about the islands with us.
I thank all the group for their good company and co-operation, the less younger members for their tremendous determination and fitness to spent so much time on foot, and Pam for the endless supply of sweets.
