New Housing: Swift Bricks

Debate between Caroline Nokes and Kerry McCarthy

Monday 10th July 2023 Westminster Hall

[Kerry McCarthy (Bristol East) (Lab)]

It is a pleasure to serve under your chairmanship as always, Sir Edward. I congratulate Hannah on bringing this petition forward, and I thank the hon. Member for Stockton South (Matt Vickers) for introducing the debate. It was a real privilege to be asked by the RSPB, quite a long time ago now, to be the species champion for the swift, but I am clearly not the only one—this whole room is full of champions for the swift. I think I rather lucked out in being chosen ahead of them. We have heard so much about what an amazing bird it is, so I will not go over that ground again.

Soon after taking up the role of species champion, I went to visit Bristol Swifts and saw the dedication among these local groups. A couple had spent seven years trying to attract swifts to their homes. Having put in the bricks and played mating calls, they finally managed to get the swifts to come, and last year their swift boxes provided nests for 16 breeding pairs and 36 chicks. That is just in the one home.

There are many other amazing groups. Particularly over the past year or so, I have seen on Twitter how many there are in localities such as Rother, Hastings, Lewes and Sheffield.

[Caroline Nokes]

I apologise for intervening a lot, but it would be remiss of me not to congratulate Hampshire Swifts on its work. I opened a conference for it back in 2018, and it has contributed to the planning process and fed into the local plan review. Groups such as that are doing so much to push this issue; it just requires the Minister to push it over the line.

[Kerry McCarthy]

It certainly does. I was going to mention Hertford and Halesworth, and now I can say Hampshire too. Cambridge also has a group.

I pay particular tribute to Save Wolverton’s Swifts and Martins, which has a special place in my heart because it is run by my sister, who is in the Public Gallery. That shows the difference between us: I am always here talking about things, and she is actually out there doing things. That group has provided 170 new homes for swifts since 2020, and this year swifts have finally taken up home in her house.

Last year, because the heatwave made the bricks too hot, there was a real problem with fledglings trying to leave before they were ready to fly. All around the country, local groups rescued swifts; my sister cared for 17. I remember going down to Sidcup to pick up her daughter from university, and as the three of us sat outdoors at a Sri Lankan restaurant, there was a swift on the other chair being fed crickets—it had to be fed every hour to keep it alive. My sister did that while juggling three kids and working a full-time job.

An interesting fact is that a swift weighs the same as a Cadbury’s creme egg. Save Wolverton’s Swifts and Martins is making egg cosies to raise funds for swift groups. If anyone wants one, I am sure I can arrange that.

I also want to thank Milton Keynes Swifts, which works very closely with Save Wolverton’s Swifts and Martins. I thank Mike LeRoy for sending me a comprehensive briefing about the work that group is doing with developers and housing associations. It was particularly helpful on biodiversity net gain, which I will come to in a moment.

As we have heard, when a building is demolished or renovated, swifts lose their nests, and new buildings do not always offer the same nooks and crannies. That habitat loss is one of the reasons swifts are now red listed. They are a conservation concern, as their numbers fell by 62% between 1995 and 2021.

Other Members have explained effectively that swift bricks are very simple and easy to use. They blend into the building and do not affect insulation. That issue has been raised with me, particularly given the discussion at the moment about the need to retrofit homes, but the bricks will not have an impact on the energy efficiency programme. They are durable, low cost and do not require maintenance. Even if they do not attract swifts, they can be beneficial for other red-listed species such as house sparrows, starlings and house martins. Hibernating tortoiseshell butterflies and bees also use them.
