Thanks to the BTO's Cuckoo Tracking Project we are learning more about Cuckoo migration. There are still important questions to answer, so we have fitted four more Cuckoos with satellite tags this spring. Senan, Valentine, Tennyson and Nussey join eight existing birds, all of which should make their way south during the next few weeks. Follow their exciting journeys.More Details
This set of indicators, published today, uses data collected by BTO volunteers. Covering the period between 1970 and 2016, the five wildbird indicators show mixed fortunes. Farmland bird populations continue to fall, woodland birds are down, some groups of breeding water and wetland birds are bouncing back, seabirds are up and down against a backdrop of decline and many wintering waterbirds are declining after several decades of increase. You can read more here.
July is a fantastic month for birding. Some species will have already finished breeding and will be making their way south with this years offspring to their wintering grounds. This can bring lots of rare and exciting birds to the UK, particularly around the coasts, but also to some inland locations. Check out the latest BTO migration blog
Issue 7 of LifeCycle includes the results from the 2017 breeding season, generated from the NRS, CES and RAS results. It also features articles on turning a Tree Sparrow project into a RAS, monitoring Swallows, devising a Corn Bunting nesting project, mentoring nest recorders, recording other taxa in your nest boxes, House Sparrow terraces and much more.
Citizen science is increasingly recognised as one of the most cost-effective means of achieving large-scale and long-term biodiversity monitoring. Historically, changes in habitat or land cover have been recorded through two main approaches: professional field data collection and remote sensing using satellites. Might Breeding Bird Survey (BBS) data be useful for monitoring habitat as well as birds? Read more here.
July is a quiet month on most inland waterbodies, with many birds on nests or with fledged young, but please remember not to count these young birds on your monthly counts until they are 2/3 grown. Wetland sites will begin to see the start of the return wader passage depending on water levels with Green Sandpipers being one of the first species to appear. Although generally a quiet month for rarities around waterbodies, occasional vagrants such as Lesser Scaup, Collared Pratincole or Marsh Sandpiper or maybe even a real rarity such as a Red-necked Stint may turn up. Stay safe and enjoy your WeBS Count!
The latest figures from BTO, just published in the Journal of Applied Ecology, give us a total of between 5,095 and 5,983 individuals distributed at sites spread across the south and east of England, with Lodge Hill in Kent identified as the most important site for this iconic species.

The UK Cuckoo population is in decline and we are using the latest satellite-tracking technology to help us understand why. We currently have 14 satellite-tagged Cuckoos and all have now left the UK on their migration south. Who will be the first to cross the Sahara? Follow the Cuckoos on their perilous journeys to central Africa.
This spring, scientists at the BTO have been out catching and fitting satellite tags to Cuckoos once again. Ten birds in all have been tagged in a number of different locations that include the New Forest, Knepp Estate and Carlton Marshes in Suffolk. They have all been named. Follow Bowie, Sylvester, Cameron, Lambert and all of our Cuckoos as they begin their journeys south.
With just over a week to go, Spurn Migration Festival 2018 is almost upon us. With easterly winds coming straight out of Scandinavia forecast for the Migfest weekend it could be one of the best yet. Online ticket sales close at midnight on Tuesday 4 September. Don’t miss out, get yours from the Migfest website.
Records from approximately 11,000 BTO Garden BirdWatchers indicate that Bullfinches are being seen in more gardens than ever this year! Bullfinches were seen by 19% of Garden BirdWatchers in April 2018, which is almost double the average (1995-2017) for this month. These figures follow on from a record high last winter, after a successful breeding season. Our Annual Results for 2017 show a 16% increase in the percentage of gardens reporting them compared to 2016. See the full Garden BirdWatch Annual Results.
The latest WeBS report, Waterbirds in the UK 2016/17 has been published. Read the report at http://www.bto.org/wituk and explore all the data and trends - including brand new facilities to explore waterbird totals for all WeBS sites and display up to four low tide maps at once - at http://www.bto.org/webs-reporting
The latest report includes articles focusing on Teal, Greenland White-fronted Goose and the waterbirds of reedbeds.... read more
Widely recognised for his work on the study and conservation of owls and raptors, biologist and professional ecologist Colin Shawyer has collaborated with the BTO on projects such as Project Barn Owl (1995-1997) and the Barn Owl Monitoring Programme (2000-2009). As founder and co-ordinator of the Barn Owl Conservation Network (BOCN), Colin is in contact with Barn Owl ringers and nest recorders across the country and oversees the annual monitoring of over 3,000 nest boxes.
This year I thought it would be interesting to relay my findings on a regional basis. Most of you know that since the early 1990s I have been monitoring Barn Owl nests from Yorkshire through the eastern, midland and central southern counties of England to Kent and... read more
The winning ticket numbers have now been drawn for the Spring Raffle 2018 and can be viewed here. Winners are currently in the process of being contacted. A massive thanks to everyone who took part and helped to raise almost £42,000 in ticket sales and donations to fund our work looking out for birds.
During the weekend we received locations from the tags of PJ and Selborne that showed they had both arrived in France. PJ is currently only 553km from home, whilst Selborne is a little further away at 811km. Whilst it looks like PJ could arrive back first, Selborne could still win the race. Follow them both home.
The latest Breeding Bird Survey report, which has just been published, shows a 66% increase for Spotted Flycatcher during 2011–2016 and a 21% upturn for Willow Warbler in Scotland over the last 23 years. In England, both of these birds are in trouble. Read the full 2017 BBS report to find out more.
2018 marks the 90th anniversary for BTO’s longest running survey, which has been carried out annually since 1928, and, as far as anyone is aware, is the longest for any breeding bird in the world. To celebrate BTO is asking birdwatchers to tell them about any heronries they see; adding even more information to this incredibly long-running study. Heronries can be added by clicking on the location in the vacant sites map.
Due to bad weather being forecast, we've decided to postpone the Thetford event on Saturday March 17 till next Saturday, March 24. To attend you will need to book free tickets again using the new event page.
We apologise for any inconvenience caused, and hope to see those that can attend next week.
