One of our visitors came in to the centre to report a fantastic view of an otter playing in Ivy Silt Pond yesterday morning – of course Michelle and I went to have a look a couple of times over the course of the rest of the day and, of course, were disappointed. What was particularly noticeable (other than the lack of a large mustelid!) was the complete absence of birds on the pond:
This morning it was one of the first things I checked after a I arrived and was greeted by the usual array of mallard, coot, tufted duck and cormorant so I could be fairly confident that the otter, if still around, was at least lying low.
I did check one of the habitual spraint sites (otter are very territorial and, like many other mammals, use their faeces as boundary markings) and was treated to the sight (and scent!) of both tracks and spraint:
Top-tip! Otter and mink spraint look very similar, and, due to their shared habitat preferences and diet, will be found in similar locations, but mink spraint has a very powerful unpleasant smell and will often contain more mammal remains than fish (including hair)whilst otter spraint is composed primarily of fish bones and scales and has a pleasant fresh fish smell, which is even likened to the scent of jasmine tea!
Other current wildlife news include reports of a mealy redpoll at the woodland hide feeding alongside the lesser redpolls, marsh tit (again at the woodland hide) and two black necked grebes on Ibsley Water. The great white egret is still with us at the moment, but probably won’t be for many more weeks as it is about time that it headed back south to France. Already seemingly departed are the starlings that entertained everyone so spectacularly before Christmas and also the Ivy Lake bitterns. I am not surprised that the starlings have moved on as in previous years (with substantially smaller murmurations admittedly) they have usually gone by this time, but it is unusual not to have bitterns now – but of course it has never actually been significantly cold for a significant time as yet this winter and on top of that the rain over the last few weeks has really impacted the lake water levels. Having said that it maybe that there are still bittern on the reserve, but rather that they have just moved elsewhere, or even if they have left it is entirely possible that they, or others, return in the event that winter actually kicks in and we get some cold weather over the course of coming weeks.
Otherwise everything is as you would expect but for once the sun was shining:
All this week I have been aware that the song birds are becoming more vocal – particularly things like the great tit, blackbirds and robins, and today in the sun shine, that was particularly the case. Even the great spotted woodpecker joined in with a drum roll this morning! Additional evidence of the passing of the season are the snowdrops by the centre:
