A slightly broken down frozen bolus.#apusapus #commonswift #actionforswifts #swiftconservation #saveourswifts #swiftconservationireland #northernirelandswifts

The results are very limited and show in the case of the bolus what the adult was collecting before returning to the nest .For the droppings analysis I had to collect c20 droppings from below the best boxes. It's just a snap shot of the days leading up to me collecting them.

I sent away a bolus I found beneath a nest box

I had to send c20 droppings away to be analysed for insect remains. It's just a snap of what was brought to the young when they were 4 weeks old

A couple of charts to show what swifts eat. #apusapus #commonswift #actionforswifts #swiftconservation #saveourswifts #swiftconservationireland #northernirelandswifts.

Swift activity at the house last night.#apusapus #commonswift #actionforswifts #swiftconservation #saveourswifts #swiftconservationireland #northernirelandswifts

Still going up

Hottest day this year in a swift nest box

32 days old and looking great. 2 weeks left and they'll be gone.#apusapus #commonswift #actionforswifts #swiftconservation #saveourswifts #swiftconservationireland #northernirelandswifts

It was found grounded below the colony It fledged from.

The returning swift can hardly breathe.#apusapus #commonswift #actionforswifts #swiftconservation #saveourswifts #swiftconservationireland #northernirelandswifts

how much does a swift bolus weigh? This one is 3g which is 8% of an average swift's weight. That's the same as me carrying a 1.1st/7kg bag of potatoes.#apusapus #commonswift #actionforswifts #swiftconservation #saveourswifts #swiftconservationireland #northernirelandswifts

I need another to send to @ChrisGPackham.

A swift's bolus which will be sent away to find out what's in it.#apusapus #commonswift #actionforswifts #swiftconservation #saveourswifts #swiftconservationireland #northernirelandswifts

4 weeks old today. My nest boxes are always wet. I think it's either diet or weather related. One will show off its blue darvick ring .#apusapus #commonswift #actionforswifts #swiftconservation #saveourswifts #swiftconservationireland #northernirelandswifts

2/2.Ringed with metal and darvick ring then weighed it. Just 29g! It should have been up to 50g. Just one adult feeding them. The rings! Where'd they go!? Both fell off in to the grass. I decided to put both back and and not proceed.

1/2.Out ringing swifts yesterday I was shocked to find a dead adult in a box. Two healthy point of fledging young until I lifted one. It felt light. #apusapus #commonswift #actionforswifts #swiftconservation #saveourswifts #swiftconservationireland #northernirelandswifts.

Swifts always greet each other when entering a box. They never know who might intrude. No greeting expect a slap.#apusapus #commonswift #actionforswifts #swiftconservation #saveourswifts #swiftconservationireland #northernirelandswifts

An intruder in a nest box occupied by a non breeding pair. Residents run straight to the nest. Intruders literally panic and look/act nervous.#apusapus #commonswift #actionforswifts #swiftconservation #saveourswifts #swiftconservationireland #northernirelandswifts

Take that said an adult swift I ringed this evening. It was found in a cupboard after falling down through a gap
