Our door knockers are handcrafted so there may be some subtle variations from the images. Each piece is truly unique, engraved with our trademark and finished to order.

Please select your finish. Scroll down for information on finish options.

The name Cosima means ‘order’ in Greek; very apt for our industrious, perfectionist woodpecker. She’s the embodiment of our belief that beautiful art can be matched with functionality. Unlike other woodpecker door knockers, she raps with her tail producing a lovely resonating sound. Cosima has fine feathered detailing, feels smooth to the touch and fits naturally in your hand. She has a specially modified bracket that ensures her beak does not touch the door (no matter how hard you knock!)

This woodpecker door knocker brings a touch of the countryside to any front door.

What we love…

  • Unusual design as she knocks with her tail
  • Looks beautiful from front and side
  • Bracket does not impose on the shape of the bird
  • Ideal gift for a bird lover
  • Can’t peck your door

Fitting your door knocker

Fitted using an easy surface mounted fixing, there are no visible screws on either side of the door. Our door knockers are suitable for wood doors as well as solid core composite doors and all screws and fittings are supplied.


Aged Brass

A vintage appearance is achieved using a natural chemical-free patination process. A clear sealant is applied which protects your door knocker and prevents it from tarnishing. This is a thin and durable coating that, unlike a lacquer, will not crack or peel. It also gives protection against acid rain and salt air. No need for metal cleaning products, just wipe with a soft cloth periodically.

Polished Brass

Our polished door knockers show brass in its natural state. After casting they are highly polished until very bright and shiny. This finish can be maintained using a metal cleaner and soft brush or if left unpolished your door knocker will tarnish and age naturally. If you’d like your door knocker to remain highly polished without regular cleaning, we can add our protective sealant. Please let us know by making a note at checkout.

Raven Black

We apply a patina to the brass which creates a soft black finish that has a matt appearance. The brass is baked and the colour is left to mature before we add our sealant to protect the finish. Little maintenance is required, just wipe periodically with a soft cloth.

Satin Silver

We use a metal plating process over the brass to achieve a stylish silver with a matt finish. Our sealant is applied to protect the finish. Little maintenance is required, just wipe periodically with a soft cloth and warm soapy water

A fine piece of craftsmanship now adorns our front door

We loved the aged brass woodpecker as soon as we saw it on the Adams & Mack website. It is so elegant. Thank you for providing such a fine piece of craftsmanship which now adorns our front door. A word, too, about the wooden box in which it arrived. Everyone who has seen it has been impressed.

David Walker
Woodpecker Door Knocker

Delighted to report that the splendid woodpecker has finally been fixed to our front door after a delayed restoration and it has been worth the wait. We love it. We have a period property but wanted something which was not traditional but not overly modern either and this fits the bill perfectly. A miniature masterpiece - thank you.
