Nesting Season 101 – Hedge-cutting and the Law
Birds in Ireland are facing pressures from all sides, with habitat loss and fragmentation, predation, disturbance and climate change just some of the things they have to contend with. Nesting birds and their young are particularly vulnerable and, while it is vital that we don’t interfere with wild birds at this time, there are some things you can do to support birds during nesting season. One of the easiest ways to do so is to abide by existing laws around hedge-cutting and vegetation burning.
Hedge-cutting and vegetation burning ban
Under the Wildlife Act, it is against the law to cut, burn or otherwise destroy vegetation including hedges between March 1st and August 31st. The purpose of this ban is to prevent the disturbance and destruction of nesting sites of many of our wild bird species.Hedge-cutting
Hedges provide important nesting sites for many wild birds – including Robin, Wren, Blackbird, and Dunnock, to name a few – as well as a bounty of food for a variety of other species. They also offer shelter and safe routes for wildlife to travel along, known as wildlife corridors. Hedges offer numerous benefits to humans including food, natural property boundaries, shelter for crops and livestock, noise reduction and visual appeal. As healthy hedges also sequester and store atmospheric carbon, and help to slow water movement and prevent flooding, they are absolutely vital in mitigating the effects of climate change. While some green-fingered folk may argue that, with a steady hand, they can leave a nest unshaken, the sheer act of getting that close to the hedge and nests within it could be enough for the adult birds to abandon it. Without their parents, the eggs and chicks in the nest have virtually no hope of survival. If they don’t succumb to starvation due to lack of food delivery by an adult bird, they are likely to be victims of predation. 63% of regularly occurring Irish birds are of serious conservation concern, with 26% of them now Red-listed species of conservation concern and 37% Amber-listed species of conservation concern. With the decline in bird populations directly linked to the loss and degradation of habitat, it is important that we do all we can to preserve what remains. You can play your part in this by leaving your hedges alone during the nesting season, and by spreading the word to others.

Vegetation Burning
The Wildlife Act also prohibits the burning of vegetation during the nesting season. This is aimed at protecting our ground-nesting bird species in upland habitats, many of which have seen their populations plummet in recent decades. This includes species such as Curlew, Lapwing, Skylark, Meadow Pipit and Hen Harrier. While burning is not the only cause of the decline of these species, it does pose a significant threat to their breeding success when carried out during the nesting period. But even during the 'open season' for burning, out-of-control fires, can have devastating consequences on habitats sometimes 'melting' peat soils due to the heat and destroying their functions as carbon stores and sinks as well as habitats for wildlife, for years. Illegal fires during the closed period can lead to the destruction of nests and young of these already vulnerable species, as well as the disturbance of breeding adults. Additionally, such burning can damage habitats that are protected in their own right such as Raised Bog and Blanket Bog. In addition to being unique and biodiverse habitats, our bogs serve as carbon sinks, meaning that they play a huge role in mitigating the effects of climate change.

Reporting illegal cutting and burning
Despite the ban on hedge-cutting between March 1st and August 31st, it is possible that you will come across cutting and burning during this period. Indeed, the Wildlife Act does have exemptions which allow hedge-cutting during the closed period, for example, should there be road safety concerns. In saying this, regardless of who is involved, don’t assume that those cutting the hedge have received the green light to do so. It may well be that they are breaking the law. If you witness hedge-cutting or burning in any place or at any time during this period, please report it to the local Gardaí and the National Parks and Wildlife Service (NPWS). You can read the NPWS guidance on reporting Wildlife Crime here and find contact details for your local NPWS Wildlife Ranger here.Enforcement of the Wildlife Act
Efforts to tackle wildlife crime in Ireland have been strengthened in recent times. Forty-three prosecution cases were initiated by NPWS in 2023 for alleged breaches of wildlife legislation, a 39% increase since 2022. Wildlife crimes reported range from the disturbance of bats, illegal hunting, damage to Special Areas of Conservation (SACs), destruction of hedgerows and burning of vegetation within the restricted period, and more. This increase in action against wildlife crime is very much welcomed by us at BirdWatch Ireland. However, there is still work to be done. It is widely known that our wildlife legislation is not as strongly enforced as it could be, and that the initiation of cases and rates of conviction are higher in some locations than others. There are a number of reasons for this including a general lack of training and resources in the area of wildlife crime in both the National Parks and Wildlife Service (NPWS) and An Garda Siochána, and difficulty in gathering sufficient evidence on certain forms of wildlife crime. With this in mind, if you witness any other form of wildlife crime, or simply are worried about the situation for wildlife in this country, we would encourage you to also contact your local and national elected representatives to voice your concerns.

Early and Late Nesting Birds
While the ban on cutting and burning begins in March and will be lifted at the beginning of September, we strongly encourage you to leave your hedges for longer than the closed period. Unlike humans, birds don’t use calendars to determine their schedules! As the subject is understudied here, much of what we know about nesting is derived from UK data. However, owing to our milder climate, we likely have a potentially earlier onset to the nesting season in Ireland. Climate change has also caused a shift in birds' annual cycles, with milder temperatures leading some species to nest earlier in the year. We do have evidence of late nesters including the Red-listed Yellowhammer, the species with the latest fledging date. While the current legislation permits hedges to be cut from September 1st, at this time, approximately 5% of Yellowhammers may still have chicks in the nest. Hen Harrier may also still have unfledged chicks in the nest into late September. Until we have data on nest-building periods in Ireland, we advocate for a cautionary approach when it comes to hedgerow management and vegetation burning, particularly during these fringe periods.
'Last Christmas' - Birds in Irish Gardens last winter
There's still time to take part in the Irish Garden Bird Survey!! See here for more details.
If you’re a BirdWatch Ireland member you’ll have already read the results of last year’s survey in your winter edition of Wings magazine. If you’re not a member, please join and support our work! But you can catch up on last year’s Irish Garden Bird Survey results with the overview below. If this is your first year to take part in the survey, don’t worry about knowing every single species that might appear in your garden – just familiarise yourself with the most common ones to start off. If you’re a survey veteran, then see how your garden bird list compares to the national average!
Over 90% of Irish Gardens
The species at the top of the list didn’t change much from previous years. Robin, as per usual, was on top, followed by Blackbird and Blue Tit. Great Tit and Magpie moved up a place each into 4th and 5th, thanks to a fall in the numbers of Chaffinch reported. Robins can still be territorial in the winter, so are pretty evenly spread across the country, while our Blackbird population is topped up by hundreds of thousands of migrants from Scandinavia in the winter, hence their high-ranking each year. Blue Tits and Great Tits are pretty ubiquitous too, and Magpies are very effective at exploiting both urban and rural habitats.
80-90% of Irish Gardens
Chaffinch and Goldfinch fell two and three places to 6th and 10th respectively, since the previous winter, and those declines were greatest in urban and suburban gardens rather than rural ones. On the back of a great breeding season, Coal Tit moved up three places to 7th place. House Sparrows kept 8th position, and Starling made it into the top 10 garden birds for the first time in a decade!
50-80% of Irish Gardens
Wren dropped two places to 11th, while species such as Dunnock (12th), Rook (16th), Collared Dove (17th) all stayed in the same position as the previous winter. When a winter is pretty mild (the occasional storm excluded) we tend to see this stability in the rankings across many species. There was some slight movement for Woodpigeon (14th), Jackdaw (15th) and Hooded Crow (19th), all of which fell one place. The mild weather tends to mean these species aren’t forced to retreat to gardens for food as much as in other winters. Song Thrush increased by around 2% and jumped to places in the rankings to 13th. Pied Wagtail rose up two places to 18th and occurred in >7% more gardens than they did on average over the preceding five year period. Despite being very common in towns, cities and shopping centre carparks, they’re actually seen in twice as many rural gardens as urban or suburban ones. Greenfinch continue to suffer the devastating effects of trichomoniasis (make sure to clean your feeders regularly!) and reached a new low for the species in the survey – 20th place.
20-50% of Irish Gardens
While the above species occur in more than 50% of gardens, you’re in the minority if one of the below appears in your garden this winter: Siskin jumped up 7 places (8%) since the previous year. They usually start to appear in gardens from mid-January onwards, but they were making appearances from late November right through to March in most parts of the country last winter. No other species made such a big jump pup the table! One of the bigger losers was Goldcrest - down 5 places to 29th, a decrease of nearly 8%. It was a mild winter, and a good breeding season for most species in 2020, so the reason for this isn’t immediately obvious. Bullfinch dropped three places to 24th, but this might just be due to the mild winter and abundance of feeding options in the wider countryside, as they’re not a bird that visits feeders and so aren’t as associated with gardens as other finches. Other species in the 20-50% band include Blackcap, Long-tailed Tit, Sparrowhawk, Mistle Thrush and Feral Pigeon. Again, not species that tend to avail of bird feeders with any regularity, but species who know how to make a good living in a human-dominated landscape, be it rural, urban or suburban.
Best of the rest
Despite being a non-native species, Pheasants tend to be seen in 15-20% of gardens each year, which is surprisingly high considering they don’t tend to breed well in the wild, so are reliant on being released by gun clubs every autumn. Buzzards moved two places up the rankings and are seen over 15% of gardens each winter. Herring Gulls were in 11% of gardens, Black-headed Gulls in 4%, and 1.3% of gardens had some sort of gull visiting but weren’t sure what species! Great Spotted Woodpeckers are one of the most recent additions to our bird community, and over 4% of gardens had one visiting their peanut feeders (it’s always peanut feeders!) last winter. They’re now breeding in almost every county in Ireland, so expect to see them charging up the rankings table in the coming years. Last year was a mast year for acorns, which meant Oak trees were providing a huge bounty for species such as Jays, and as a result they were seen in fewer gardens than usual (8%, down 1% from the average). This tends to happen every few years. Lastly, Redwing and Fieldfare, our two wintering thrush species, both dropped a bit, thanks again to the mild winter.
See below for the full Top 30 birds in Irish gardens last winter, and their various ups and downs since the previous year. Most gardens record between 10 and 25 species over the course of a winter. Whether you have more or less than that, we still need you do to the survey!
