Personally I have long had a fascination for nests; indeed, birds eggs provided an early rational for going out into the field when I was much younger. A book called ‘Finding Nests’, by Bruce Campbell opened my eyes, for it included details of the BTO nest record scheme and samples of that famous green card. I was hooked, in part because my initial letter of enquiry (at the age of thirteen) produced such an encouraging response from Henry Mayer-Gross, the Nest Records Officer at the time. Nest recording was for many years my most absorbing birding activity. Now I have retired, I look forward with sweet anticipation to the coming spring. I have already noted two Blackbird sites, a Collared Dove and a building Dunnock, around my garden. Sadly, not everyone we meet out birding has the birds’ best interest at heart. As ever, please be very careful about passing on information regarding breeding birds, no matter how common, to birders you do not know very well indeed! Good birding, Norman News and announcements Obituary Announcements It is with regret that we acknowledge the passing of two former officers of the society recently. James Allen was made an Honorary Life Vice-President in 1976. He was the recorder for West-Central from 1955-57 and assisted with editing the KBR in the period 1959-61, but will be remembered as treasurer from 1956-75.Jim Martin passed away on 22nd January 2015 at his home in Shropshire after a short illness. He was a life member of the K.O.S. and a splendid, hardworking Chairman of the Society for 10 years throughout the 1990s. Full obituaries will appear on the KOS website in due course and their passing will also be recorded in the KBR for 2015. 3 Ruddy Ducks There has been some discussion recently in birding circles regarding submission of records for this species, given its status as ‘public enemy’. The Records committee would like to state that any records submitted to the KOS will not disclose exact details of localities of breeding birds. The full text of clarification from the Rare Birds Breeding Panel sent to county recorders is placed below. Barry Wright – Chair E&RSC The Rare Breeding Birds Panel does not hold a view on the rights and wrongs of the cull but one of our objectives is to be able to provide the best possible information on population status for all species with fewer than 2000 breeding pairs in the UK. The Ruddy Duck is clearly one and we hope that all county recorders will do their best to be able to provide accurate, annual, totals of breeding pairs at the county level. This would include pairs in breeding habitat which may not be confirmed breeding later in the season (due to lack of follow up, no breeding having taken place, or the birds being shot) as well as any that were confirmed breeding pairs. In our most recent report on non-natives we put the minimum breeding population of Ruddy Ducks as 24 pairs (2011) You will know from our published reports (in British Birds) that we do not name sites and in some cases we provide totals only at the regional level (rather than by county) to better protect the location of breeding birds – this may be necessary for Ruddy Duck when we next publish the rare non-native breeding birds report (covering 2012-2014), if indeed there are any breeding Ruddy Ducks to report – very few records have been submitted for 2012 or 2013 so far! So I would ask all recorders to encourage their observers to submit their breeding records to you (in confidence) and for you to summarise these at county level and submit county totals to RBBP. Although we always request site data we appreciate that you may not have these yourselves. If any data for 2012 or 2013 is available but was overlooked in the annual data submissions to RBBP for those years, we would always welcome such records if they were to come separately. The advantage of doing all of this is that at some point it would still be possible to document the status of Ruddy Duck in the UK in some detail because the data for the period since 2009 will have been securely archived in one place – with RBBP Mark Holling, Secretary of the Rare Breeding Birds Panel 4 New Technology! The KOS has something called a ‘Facebook page’ which we are keen to use more frequently in order to update members and potential new members on latest developments in the KOS, discuss bird sightings, meetings, publications. The KOS wishes to embrace modern technology and this will serve as another means to keep in touch with the KOS and birding in Kent. Articles FLOCKS Knot, Bar-tailed Godwit and Grey Plover by John Whitting We are always seeing flocks of birds, but flocks vary according to species and circumstance; they may also comprise one or several species. They may stay together all the time or at specific times. They may feed and fly in tighter or looser groups of a few to many thousands. They are drawn together for different reasons. Some species never flock; others are rarely sole. Most behave differently according to season - breeding, winter or passage. Some waders are keen flockers, both at a source of food and at high tide roosts. Some of their huge closely packed flocks are spectacular in their manoeuvres. 5 Knot and Dunlin form the tightest masses in the air, and on the ground at roost. Oystercatchers, godwits and Curlew feed as individuals, but pack together in dense masses at roost. Oare Marshes is the best place to see Black-tailed Godwits form a rich brown carpet of up to 2000 birds on the pools at high tide especially in July and August. Elmley is the best place to see the sky darkened by thousands of Lapwings and the more densely packed Golden Plover. These congeners often form mixed flocks on the fields and take off en masse; all of a sudden the air is full of birds. Is it a dread or a ground predator or is it a raptor? It is difficult to look for one offending Peregrine and count the waders at the same time in this great avian spectacle. Other waders congregate rather than flock; best examples are Snipe and its little cousin Jack, Green, Common and Wood Sandpipers and Ruff. Redshank and Greenshank roost communally, but Greenshank and Spotted Redshank will feed co-operatively where suitable prey is present. Wigeon, by John Whitting Geese, some ducks and other large birds form noisy flocks often in V formation for aerodynamic reasons. Anas ducks are good at flocks. Our top flocker is the Wigeon, with impressive winter gatherings at Dungeness and especially Elmley, but Teal form more compact and wader-like flocks. Tufted and Pochard gather in hundreds at a number of sites in the county in both mixed and single species flocks. They are congeners, but Pochard are largely vegetarian, feeding on the weed which harbours the fresh water mussels on which the Tufted feed. Moorhens gather, rather than flock. Coot gather in larger rather scattered groups, but Abberton Reservoir used to host a black 6 mass of 2-3000 tightly packed Coot. Both Rooks and Jackdaws breed colonially, roost together and often feed together. Carrion Crows and Magpies merely gather to exploit a food source, but each species will roost communally. Birds of Prey are often solitary and eagles in particular enjoy large home ranges. Others such as Lesser Kestrels and Red-footed Falcons are social feeders.
