The weekend’s wildlife highlights were; Minke whale, many Common Dolphin and 20++ Harbour Porpoise mostly feeding a mile or so offshore with an attendant “frenzy” of seabirds! Oddly this frenzy is mostly Shearwaters – over 2000 Manx, up to 100 Great (counted from Gwennap Head), c.200 Cory’s , 50++ Sooty, and increasing numbers of Balearic Shearwaters – 5 from our Minack trip on Sunday evening. There are relatively few Gannets associating with this frenzy which implies the birds are feeding on small prey such as sand-eel or fry, fine for the Minke Whales but unusual for dolphins. A few presumed Blue-fin Tuna have been feeding in the same area and, although still not numerous, Ocean Sunfish are increasing again with 4 on Sunday.
Seabird numbers continue to be impressive! Out of the totals mentioned above we have managed to see 3 Cory’s, 2 Great, 5 Sooty, and 5 Balearic Shearwaters amongst the 100s of Manx on the Minack trip, a few Storm Petrels are still appearing well inshore and we saw over 20 following a returning “day-boat” on our 3pm cruise. Although not many are off towards Land’s End 100s of Gannets are still in the Bay area though lately further east off the Lizard. Auk numbers have dropped sharply as the adults are now taking newly fledged young to safety offshore. Skuas are still scarce with only a couple of Bonxies (Great Skua) harassing the shearwater flocks, and although a few Sandwich Terns and Kittiwakes are in the bay there has been little movement so far. Great Northern Divers and the mad/sad Eider drake are still with us, and small flocks of Common Scoter are still passing with over 30 this weekend. A couple of Yellow-legged Gulls are still arriving , but since the strong westerlies have set in there have been fewer Mediterranean gulls.
The Grey Seals are slowly building in numbers on St Clement’s Island again, but we still see too many kayakers getting too close and disturbing them- 2 people even had to be taken off the island by the lifeboat apparently! Wader numbers are already building with Curlew, Whimbrel, Oystercatcher, Turnstone, Dunlin, an early Purple Sandpiper and Common Sandpipers all roosting on the island so this disturbance is even less welcome!
All in all it has been excellent for so early in the season and we even had a report of a Basking Shark from one lucky observer on the 1pm fishing trip! So even though the weather isn’t exactly scorching, the marine wildlife is certainly heating up!
