As well as our Wardens and volunteers from Wensum Valley Bird Watching Society reporting their sightings, regular visitors to Pensthorpe keep us up to date with what they have spotted.

What to look out for in May

Sedge Warbler 

(Acrocephalus schoenobaenus)


(Hirundo rustica)


(Sitta europaea)

Sedge Warbler song includes wheezes, whistles and a series of quite harsh scratchy notes.

The reserve hosts eight species of warbler in the spring and summer months.


They travel to the park from as far away as South Africa (approx 6,000 miles)

They breed in the park and can be seen catching insects whilst in flight.



Also known as the “Mud Dabbler” due to its habit of reducing the size of its nest hole using a layer of mud, the Nuthatch is common in the Park’s woodlands.

Nuthatches have strong feet with sharp claws which enable them to move both up and down the trunk of trees with ease.



 Common Bluebells

(Hyacinthoides non-scripta)

Common Blue

(Polyommatus icarus)

Banded Demoiselle 

(Calopteryx splendens)

The woodlands in the park are carpeted with Common Bluebells in May.

It can take up to seven years for a colony of Common Bluebells to become established. Almost 50% of the worlds Common Bluebells are found in the UK.



The Common Blue butterfly is the most common of the blue butterflies to be found in the UK. It is a small butterfly seen regularly in grassy areas flying low above the ground.

They are similar to the Holly Blue, but the Common Blue has white bordered black spots and orange marks on the underwings.


Banded Demoiselles are found along slow running streams and rivers.

Whilst they differ in colour, the males being blue and the females green, they are both stunningly beautiful damselflies.
