Temperatures on the red side of zero if only by a small handful of degrees, no night time frosts and rain mean that spring is creeping along. There might still be lots of snow and ice but there are also now snow free areas even in Maridalen and a few birds are arriving. This morning’s dog walk revealed a singing Chaffinch which brought an uncontrolled smile to my face – maybe this world, and the bits that we humans don’t control is not so bad after all 😊
I have now seen two of the S’s in Maridalen with yesterday a number of Skylarks heading south (and a couple singing) after I think having met a wall of fog to the north and two Stock Doves doing the same. Mistle Thrushes, only the Dales’s third ever Rock Pipit, Merlin, Peregrine and migrating flocks of Whooper Swans have also suddenly announced the arrival of spring. As I write this there are strong southerly winds and more rain so I would not be surprised if a number of new birds arrive today. Maybe Maridalen will also get in on the Stonechat act? There is now a pair at Fornebu and with so many birds turning up surely we will find them breeding soon.

some sights and sounds from Maridalen yesterday:
Yesterday also saw me on a wild, and successful, goose chase. With no GPS trackers to help I can no longer use my phone to find the Taiga Beans but that didn’t matter as I tracked them down on two fields totalling 65 birds in total. I also had a number of early Pink-feet, two White-fronts and three Tundra Beans alongside Greylags, Canadas and hybrid between the two so it was actually a very goosy day.
The Taiga Beans were on stubble fields I have not found them
on before although were in the same areas as previous years sightings and were
also close to Whooper Swans and other geese whereas often they are alone. They
were also relatively close to roads allowing themselves to be well watched and
were surprisingly unskittish.
It was also noticeable that they were not together in a single flock. The first birds were 16 in total and were on a field close to where the birds regularly were in both spring and autumn last year and were spread out across a field with 140 Whooper Swans and Greylag, Canada and two White-fronts as you can see in this video.
After a while when they decided (for no apparent reason) to fly off and did so in groups of 4,4,5,2 and 1 with the last three groups eventually joining up and then turning around before flying back over the field and disappearing to the NE although these birds had returned later in the day and were again separate on the field as groups of 5,2 and 1. Amongst the group of 5 I saw bird V7 who has lost its neck collar but still has a colour leg ring.
 |
| V7 left leg probably with its family given how the group of 5 kept to themselves. This bird was ringed in Scotland in Nov 22 and I have seen it every spring since then but interestingly not in the autumns |

| Taiga Beans keeping separate and probably two family groups |

The second group of 49 birds was on a stubble field close to Udenes Church. The river here is where they roost but I have rarely seen birds on the fields here. A large flock of Whooper Swans has been here this week and maybe this attracts birds – it is very likely that I was watching very newly arrived birds. When I first saw them they were split into distinct flocks of 30 and 19 and there was in addition a small flock of Pink-feet which had a Tundra Bean amongst them. It was very interesting to see how these three small flocks were within 20m of each other but operated as distinct units. On a return visit 2 hours later though the geese were all mixed up. I was now able to find another leg ring Y7 but no collars.

This video shows both the ringed birds:
So, 65 Taiga Beans in total with two leg rings but no collars.
Hopefully there are more birds to come and the flocks will join up. It would
make a lot of sense that the birds at Udenes were new in from Denmark that
morning whereas the other 16 have been around a few days (I had 12 on 5.3 then
2 on 8.3 and 4 on 9.3 which may have been the flock of 16?).
The Tundra Bean Goose was educational to watch. When I found it amongst the Pink-feet it was clearly a Tundra due to being the same size as the Pink-feet and also the fact it was associating with them rather than the Taigas. On the return visit when all the geese were mixed together I did find it again BUT I doubt very much that I would have been brave or foolish enough to have called it as a Tundra if I had not seen it separately earlier. I have always been very conservative regarding reports of Tundras within flocks of Taigas and have dismissed other reports due to the individual variation amongst Taigas but of course it is possible for birds to get mixed up especially if Pink-feet (the more likely carrier species for Tundras) are mixed in. I had a pair of Tundras at another site amongst a large flock of Whoopers where there were also Pink-feet, Canadas and Greylags but no Taigas. The feature that was perhaps easiest to pick out the Tundra was that its head was paler than the heads of the Taigas which were noticeably darker than their necks. Whether this is a consistent (and previously described) feature is not something I am aware of.
These videos allows good comparison of the Tundra and Taigas:

 |

 |
| these pictures could have been sharper but give an educational comparison of the two |
 |
| this is probably the best with the smaller size of the Tundra apparant as well as the paler head. Bill structure is of little use but we see the shorter neck |
 |
| and here with a Pink-foot |
 |
| the bird on the right could very easily be mistaken for a Tundra due to short neck and stubby bill but note the darker head and I am sure it is "just" a female Taiga |
 |
| and two Tundra on another field which I did not see side-by-side with other geese but look to be larger birds than the other one. Notice the pale head which is concolourous with the neck especially on the left hand |
 |
| and Cranes (trane) are back although only no large flocks yet |
