The next 30 days are crucial for monitoring the Sussex Honey-buzzard population and I’d very much welcome any details of sightings as well as photos, including from published viewpoints, by email. Please only use social media for sightings from published (in “Where to Watch Birds in Surrey and Sussex”) viewpoints and give only numbers, in line with the Bird News Services. Thank you.

As mentioned in my “Recent Sightings” post on 16 June, I’m trying to find out whether we may be able to increase our fragmentary knowledge of breeding Hawfinches in Sussex by looking for them in summer in cherry trees, and by looking for split stones under these trees (brambles and nettles permitting!). If you know of cherry trees in fairly rural areas that have plenty of fruit (many don’t), I would be very grateful if you could check for split stones (photos would be useful) and perhaps look for birds themselves. Hawfinches are feeding recently fledged young in Sussex at the moment and can be slightly easier to see at this time. Some are being found in cherry trees. Early morning is best if you are hoping to see them. If you can help, even if you know of suitable trees but can’t visit, do please let me know. Thank you. Mark Mallalieu, mallalieum@gmail.com.

The BTO/RSPB/NE Heathland Birds Survey includes Tree Pipit as one of the species for which records are requested in addition to the three focal species (Nightjar, Dartford Warbler and Woodlark). To obtain a fuller picture of the breeding distribution and population of Tree Pipits in Sussex, the SOS would also very much welcome all records of Tree Pipits in non-heathland breeding habitat in the county in 2025. Small numbers of Tree Pipits breed on non-heathland sites (e.g. scarp downland and young forestry plantations).

The first Tree Pipits will be arriving back on territory any day now, so we are asking you, especially if you know of such sites occupied by breeding Tree Pipits in recent years, to look for the species up to mid-July and enter records (other than any collected in the course of Heathlands Birds Survey work, including Woodlark surveys on farmland, for which there are separate data entry procedures) on Birdtrack, eBird etc. Please add breeding evidence and a note of the habitat. Thank you.

At some nests in southern England there is very little wasp comb this year, though one had lots, suggesting that some, but not all adult Honey-buzzards may be relying more on frogs than is usual for this stage in the breeding season. Nevertheless, it seems to be a good year with 15-16 pairs found so far in the county and c.12 breeding, a high proportion. Over 50 different adults have been seen – thanks for all the photos that you are sending me and please keep them coming.

There’s been an excellent response to the SOS request not to publish photos of adults carrying food. Thank you. Please follow the same guidance with regard to juveniles at breeding sites, though photos in confidence to me will help determine breeding success. If you wish to see juveniles, they could be flying soon and certainly by mid-month. It’s well worth reminding yourself what juveniles look like: they soar on level wings like adults but the overall structure is like a strange mix between an adult Honey-buzzard and a Common Buzzard, so they can be very confusing when you first see one. The juveniles may remain in the Sussex breeding areas until early September.

I hope that many of you have enjoyed watching Honey-buzzards in Sussex this year, perhaps for the first time, following the publication of a few watchpoints. I’ve been coordinating population monitoring work for several years and the effort in the field is considerable. Following the publication of sites, I wondered whether I could rely on the birdwatching community to cover at least some areas this year and this has indeed happened, with excellent coverage of two sites. As a result we have a good understanding of activity and numbers, without additional dedicated effort being needed.

We know of 13 territories so far, most with pairs, so it’s shaping up to be a good season. The adults are finding plenty of wasp comb and are taking frogs as well.

The published viewpoints were chosen to avoid overlooking nest sites and the Bird News Services have been exemplary in following  the guidance from the Sussex Ornithological Society about not revealing evidence of breeding, beyond birds being present in an area. Posting photos on social media of birds carrying food should be avoided as a precautionary measure. Hitherto, such photos would have been fine if the location was not given (I have done this on several occasions), but there is still some risk in cases where the location can be deduced, and it is best that we all now err on the side of caution. However, do send such photos to me or the County Recorder recorder@sos.org.uk to help us monitor breeding activity. If you take a photo that shows a readable ring number (two black letters on a white background) that would be brilliant.

For the more adventurous, there are still several sites that were published in the recent “Where to Watch Birds in Surrey and Sussex” that have not been searched as far as I know, so why not try to find out something new about these splendid birds at one of those.

No illegal activity, e.g. nest disturbance, has been reported in Sussex but it could happen. Please let me know if you see any suspicious behaviour or illegal disturbance. Thank you.

David Campbell has set a high standard as our County Recorder since 2020, drawing on his outstanding knowledge of birds and bird identification. He has combined this voluntary role with a very busy working life, but decided recently that the time had come to stand down. The Society is extremely grateful to him for all he has done during his tenure. David Thorns kindly agreed to take over as Recorder, effective from 1 August. David is a very experienced birdwatcher who lived in Sussex for many years before moving to France. He is well travelled overseas and has had several articles and letters published in birding publications such as Forktail, Cotinga and British Birds.

David is now back and based in Eastbourne. He has become familiar with the local birding scene and quickly established his birding credentials by finding several notable birds in the area including two firsts for the county, for which many SOS members have been most grateful. We wish him all the best in his new role and the Society will of course give him all the support he needs as he settles in.

If you have volunteered to do a bird survey on Ashdown Forest this spring and summer, the Conservators will allow free car parking for the purposes of the survey and for the period of the survey. If you’d like to take advantage of this, and have not already done so, please email me your car make, model and registration as soon as possible, preferably within the next few days. Please also say which survey(s) you are volunteering on. Thank you. Mark Mallalieu (mallalieum@gmail.com).

Please take a moment to complete this short survey on the White-tailed Eagle project, which is very relevant to Sussex given the frequent presence in our county of birds released on the Isle of Wight.

The latest guidance from the RSPB is here. This includes further information on the recent outbreaks and their devastating impact on seabirds as well as advice on how you can help, including by reporting dead waterfowl (swans, ducks, geese), any seabirds or birds of prey to Defra.

The RSPB update here has helpful information and advice for birdwatchers on Avian Flu, which you may find helpful if you encounter dead birds.
