Bringing back the Spoonbill

Blog by Lizzie Bruce, RSPB Senior Project Manager (seconded)

Spoonbills were once a common site across England and Wales, so common that they would be served at banquets as a delicacy. However, the draining of the East Anglian Fens and continued hunting drove the species to extinction in the UK, with the last nesting attempt in 1668 at Trimely, Suffolk.

Fast-forward three hundred years to 1997 Spoonbills attempted to nest once again in east England but it wasn’t until 2010 when a regular colony became established at Holkham National Nature reserve, in Norfolk.

Today, the UK population has increased to 69 pairs, with colonies found in Essex, Suffolk, Norfolk, Yorkshire, and Cumbria. The recolonisation is likely to be linked to the growing population in the Netherlands and the restoration of wetlands in the UK. But also, the dedication of reserve staff, in particular Andy Bloomfield, Senior Warden of Holkham National Nature reserve who has been instrumental in better understanding the ecology and behaviour of spoonbills in the UK, translating this into conservation action.
​
At the end of 2022, 50 conservationists across England came together at Holkham to attend the first UK Spoonbill Workshop. Developed by Andy, hosted by Holkham Estate and with support of LIFE on the Edge, the workshop aimed to discuss the status of the Spoonbill and its future in the UK.

We began the day with Lord Leicester, providing an overview of his family estate at Holkham, sharing insights into how the land has been managed over time and the odd recipe from old game cooking books.

The first session focused on Norfolk Spoonbills with Andy providing an overview of Spoonbills at Holkham Estate and the wider Norfolk landscape. 2022 was a momentous year for Norfolk Spoonbills with two further sites successfully fledging young. One of which was in a woodland neighbouring Norfolk Wildlife Trust Cley Marshes Nature Reserve.  George Baldock, NWT Warden, and Alice Littler, owner of the woodland, shared with us their joy and excitement in discovering breeding Spoonbills within the heronry.

Moving out of Norfolk for the second session, we hopped across the border to Suffolk which is home to the UKs only ground nesting colony of Spoonbills. With good numbers of summering Spoonbills various methods were trialled to encourage them to breed, including the use of decoy birds and artificial tree platforms. In 2019 Spoonbills opted to nest underneath the platforms! However, ground predation has been a problem, so an in-ditch predator exclusion fence was installed increasing the success of the Spoonbills and the Herring Gull colony they nest within.

We moved north to RSPB Fairburn; a site where spoonbills first bred in 2017. So far, this is the UK’s most inland colony, commuting along the M62 to feed on The Humber Estuary. With an established Spoonbill colony, plans are in place to create further safe areas at Fairburn and neighbouring wetland sites.

Finally, we moved northwards once more, with an overview of Spoonbills in the north of England & southern Scotland. Here there have been several nesting attempts within mature unmanaged wetland sites close to the estuaries. Success has so far been limited.

We finished the morning with an overview of the wintering population of Spoonbills at Poole Harbour, which currently peaks at around 80 birds. In Poole Harbour, the Spoonbills favour the less disturbed areas, so with high levels of disturbance, especially during the warmer spring & summer months this maybe part of the reason as to why they have yet to stay and breed in recent years. 

After lunch we enjoyed a pre-recorded talk from Petra de Goeij, who provided an in-depth overview of Spoonbills in western Europe. The population has grown from 500 pairs in the mid 1980’s to approximately 9500 pairs today. On the mainland in Netherland’s Spoonbills were experiencing high levels of predation, however they have since discovered the predator free islands within the Wadden Sea, resulting in the population going from strength to strength. In the Wadden sea the Spoonbill population is primarily ground nesting within saltmarshes and Herring Gull colonies.

Traditionally Spoonbills have migrated south through France, Spain, Morocco to Mauritania. However, through colour-ringing studies it has been shown that there is higher survival when birds winter in Europe, compared to migrating south to Mauritania & Senegal. Over time more Spoonbills are now wintering in the Netherlands, rather than migrating south. 

We finished the day with an overview of Spoonbill Ecology from Graham White, which neatly summarised the day’s talks.

Key take home messages
  • Spoonbills are moving into woodlands and/or scrubby islands that are currently home to breeding Cormorants, Grey Herons and Little Egrets.
  • They will make use of a wide range of tree species including Hawthorn, Willow, Beech, Sycamore, Pine,  and Elder
  • They can nest within large gull colonies on the ground, if free from predators i.e. Wadden sea and Havergate Island
  • Their diet is varied including small fish (sticklebacks & rudd), crustaceans, invertebrates, amphibians.
  • Spoonbills will travel long distances to feed, this is generally about 20km but can be as much as 60km.
  • In the UK, the estuaries and saltmarshes provide important feeding grounds for Spoonbills
  • Spoonbills will nest build throughout the breeding season including the chick rearing stage – so watch out for spoonbills bringing sticks into heronries.
  • Spoonbill young in nests are noisy – listen out for them!

 The future

For managers with breeding Spoonbills
Protect and manage your existing nesting areas ensuring:
  • Predation is minimised. This can be achieved by habitat manipulation, for example creating deep ditches around islands to reduce Fox and Badger predation. A predator-exclusion fence has been successfully used on Havergate Island protecting the breeding gulls and Spoonbills from ground predators.  
  • Areas for nesting and feeding are kept disturbance free.
  • Maintain and enhance food supply, can you increase the availability of sticklebacks and shrimp?
  • Assess habitat quality to identify long term issues that might need addressing, for example ensuring a succession of trees to mitigate against tree die off caused by cormorants. Are there other areas of your reserve or neighbouring land that could 

For managers of potential Spoonbill breeding sites
  • Identify future potential nesting sites in strategic locations – where are Cormorants breeding? Where are the heronries?
  • Consider creating new sites in strategic locations, for example Spoonbill islands have been created at RSPB Titchwell on the Norfolk Coast.
  • Where heronries exist, how could these nesting locations be enhanced – do they require additional ditching to protect the islands or is there an option for predator-exclusion fencing? Where might the Spoonbills feed? Can you enhance food availability by flushing high tidal flows in the spring on a shallow lagoon to bring in sticklebacks and shrimps that move into shallow /fresh waters to breed?
  • Consider trying artificial trees, platforms and decoy birds – to date this has had mixed success

In conclusion it was an inspiring day, bringing together conservationists across England who are working on the ground to protect and restore species such as the spoonbill for years to come.
