Nature Calls

Three a.m. and nature called. Later life has so many advantages but one or two drawbacks. With the alarm set for 0520 thoughts turned to the ringing session ahead and I knew that sleep would not return. At 0500 I switched the alarm off but took great care not to wake Sleeping Beauty. 

Closer to destination Oakenclough interminable Long Lane rose to 700 above sea level as the black morning turned suddenly to gloomy hill mist and low cloud. Not exactly what the ringer ordered; Andy and I had missed another two and a half weeks of ringing due to unremitting wind and rain sweeping in from The Atlantic. 

Our last visit had been on  6 November 2020.  Nevertheless it felt good to be out again and where if the ringing was quiet, we could for sure put the world to rights via a cup of coffee, a natter and a few choice words. 

The mist cleared, reappeared and then cleared again with barely a hint of the promised sun. What a strange sort of morning with few birds on the move save for a couple of flocks of Redwings, separate groups of fifteen and a forty, plus a few stragglers. Otherwise, 15-20 Chaffinch, a Kestrel gliding through the mist and the usual suspects at George’s bird feeders 30 yards away. 

Just 10 birds caught - 3 Goldfinch, 3 Blue Tit, 2 Coal Tit and 2 Redwing. You can bet things are pretty quiet when a ringer posts a Blue Tit. 

Goldfinch - Carduelis carduelis
 
Redwing - Turdus iliacus
 
Blue Tit - Cyanistes caeruleus

Unlike recent weeks the weather looks fairly settled for a day or two so there may be chance to get some ringing and/or birding in. For tomorrow we have planned a visit to the Linnet catching site of recent years at Gulf Lane, Cockerham. We hope to clear an area of the now defunct crop to instead establish a whoosh netting area and bait it with a rape seed, niger and millet mix. 

So far this autumn and winter there is no sign of a Linnet flock and despite a number of drop-in visits, the site has very few birds. Regular readers of this blog will know of our successes in previous years by  establishing that many of the wintering Linnets in our local area originate from Scotland. Our total is 741 Linnet captures from 2016 to 2020. 

Linnets - Carduelis cannabina

Colder temperatures in January, February and March 2021 may see an influx of such individuals again and open up the possibility of catching other species like Chaffinch, Reed Bunting, Skylark and Stonechat. 

We don’t succumb so easily to quiet days; they are part and parcel of a day in the great outdoors. What would we do otherwise? Watch daytime TV for a daily dose of brainwashing?

Iceland Jobs

We were pretty keen to get out ringing this week but a steady wind of 15-20 mph made it impossible for days on end.  The usual check on late Wednesday afternoon suggested those pesky isobars might just pull apart for Thursday morning, so I arranged to meet Andy up at Okenclough for a ringing session. 

"Maybe" weather

Back home there was a hint of (unforecasted) drizzle at the off. As I drove up to Oakenclough, 600ft above sea level, the drizzle intensified with a wind from the North West at about 8-10mph. At first “light” there was 100% low cloud with light but spasmodic drizzle. 

But we stuck to the task in hand, the drizzle eased as the light improved slowly and we packed in about 11 am. During the whole time there was very little visible migration but in the circumstances we managed a reasonable catch, mainly Redwings. 

The birds caught tell the story of the morning: 17 Redwing, 4 Coal Tit, 2 Goldfinch, 2 Goldcrest, 2 Blue Tit, 1 Great Tit. 

In the heavy cloud conditions with very low visibility the visible migration of thrushes was virtually zero. We had maximum counts of 180 Redwing and 40 Fieldfare, mostly arriving from unseen directions as they dropped through the cloud cover.  Otherwise, the count of small birds was negligible. 

The field sheet shows how at least three of this morning’s Redwings were of the Icelandic sub-species, Turdus iliacus coburni, rather than the nominate European race Turdus iliacus.

Birds of the Icelandic subspecies are marginally larger and darker than nominate birds from Europe but only around 10-15% of Icelandic birds have longer wing lengths, so relatively few are separable on size. 

But this morning it was noticeable how at least 50% of Redwing wing lengths were in the 120’s rather than the mid to late teens of recent ringing sessions. The three biggest came in at wing lengths of 129 mm, 127 mm and 124 mm with corresponding respective weights of 76.5 gms, 68.5 gms and 68.9 gms. Compare these three monsters with three of the smallest – 113 mm with 56.7 gms, 117 mm with 58.9 gms, and 117 mm with 61 gms.

We’ll be trying again soon so let’s hope for a few windless days and more light for more photos.
