Trepi Trio

At last! After a week of dire weather there was a 5mph wind; although there was a gloomy, misty start, the murky skies cleared within the hour. 

I met up with Andy at Oakenclough where we expected to catch up with the species, if not necessarily the individuals, we missed in the interim. At this time of year many birds are on the move in either post-breeding dispersal or actual southerly migration. If the weather is not too good birds will fly around or above the obstacle or even delay their flights until conditions improve. Such things make for exciting mornings when we may have an idea of what species to expect in but not necessarily the numbers. 

Gloomy Start 

The early overcast may have blocked some early movement but we finished up with 24 birds of 8 species as follows: 5 Willow Warbler, 4 Chaffinch, 4 Great Tit, 3 Tree Pipit, 2 Goldcrest, 2 Goldfinch, 1 Dunnock, 1 Robin. 

We caught the five Willow Warblers early one while it was still misty but none later, suggesting that they were leftovers from Monday or before. All five proved to be birds of the year. The numbers of young Willow Warblers seem to be up this year and we speculated that the excellent summer with the lack of the usual downpours has helped ground nesting species like Willow Warblers.

TREPI is the computer input code for Tree Pipit. Inputting this morning’s data is a job for later in the day via the BTO’s DemOn, (Demography Online) an on-line application which allows users to input their ringing and/or nest records. All three Tree Pipits were birds of the year – juveniles.

As Tree Pipit breeds sparingly in the North West of England we can be fairly sure that the three caught this morning are from the Scottish population, or maybe even from Scandinavia. Maps that show the Tree Pipit breeding right across the UK are in fact inaccurate as the species' range is more limited.

Goldcrests are bang on time and we should now catch good numbers right through to November.

The young Robin showed just a hint of red breast.

There seemed to be Chaffinch on the move this morning when a few small parties flew over giving their characteristic, soft, “chip, chip” contact call.

Other birds seen during the four hour slot -  1 Great Crested Grebe, 1 Buzzard, 1 Pied Wagtail, 1 Redshank, 2 Cormorant, 8 Goldfinch, 20+ Chaffinch.  After the mist cleared and the air warmed a number of Swallows appeared, mostly heading south in singles or small parties of between 2 and 6 individuals - in all 30+.

  1. Tree Pipits have proven a bit of a nemesis for me. When I visited Scotland three years ago there were many, many Meadow Pipits and at one point where we saw several dozen feeding, several birds were perched in trees. Try as I might to convert them into Tree Pipits, I concluded that they were all Meadow Pipits that just happed to have come to rest on a branch. I have never seen a bird that I have felt confident to call a Tree Pipit. So, Phil, I expect you to put one in a box and convince British Airways (remember when it was BOAC?) to fly it over here to me. I am sure that a fellow with your post graduate training in blarney can come up with a plausible tale as to why they should transport it for free. It may cost you a little in gas and parking, to say nothing of the time to drive to Manchester or Heathrow, but that’s a small sacrifice for a fellow birder/bander/ringer/blogger. I now have something to look forward to later this week! Ever your devoted chum, David.

  3. I have learnt a new glossary: post-breeding dispersal.
    Thanks for sharing!

  4. A gloomy but beautiful start to the morning yielded those Tree Pipits and other birds...all such wonderful shots of them! Looks like a real success.

  5. I'd probably go the opposite way from what David wants.... easier to fly me over there and you take me out to see one...

  6. We are definitely experiencing 'post-breeding dispersal' - bird variety and number is much reduced from the summer, although I did manage to scare off two herons that were roosting in a pine tree before I ran past this morning! As always, love your close-ups of these fine specimens, even the scruffy robin.
