Fantasy book set on an island in the middle of the sea, there are creatures that you can only see if you have special goggles on and these creatures are at war with humans, sorry can’t remember the date when I read it (was very young)

Fantasy book set on an island in the middle of the sea, there are creatures that you can only see if you have special goggles on and these creatures are at war with humans and a creature created by a scientist finds a seagull. And if u travel to far from the island they shoot u down (we think) as they’ve been led to believe the world has ended but it hasn’t hence the seagul bit :)

One of the miss peregrines home for peculiar children series by ransom Riggs?

Storm Thief by Chris Wooding?

If not, can you narrow down the date when you possibly could have read it? When were you 'very young'? The 1960s? The 2000s?

Was this a children's book since you said you read it when you were very young?
