- ‘In 1856 Congress authorised the annexation of any uninhabited or unclaimed island from which guano could be recovered, and more than seventy Pacific and Caribbean islands were commandeered in the next thirty years.’
- ‘Between 1850 and 1870 some 37,000 tonnes of guano were mined and trammed off Middle Island to tall sailing ships bound for developing agriculture markets in Europe.’
- ‘The copious guano deposition from sea birds may play a role in maintaining the present assemblage of vascular plants on both islands.’
- ‘They roost on an offshore platform erected to collect guano (bird droppings).’
- ‘Millennia of visiting seabirds left large fossilized guano deposits on Nauru.’
- ‘He exploited the economic benefits of guano, a bird dung collected from islands off the coast of Peru and sold to Europe for fertilizer, as well as desert deposits of sodium nitrate, which was used to make munitions and fertilizer.’
- ‘They rip up bin bags, deposit vast quantities of guano on our favourite statuary, and even attack people.’
- ‘Between 1848-1875 20 million tons of guano was exported from Peru to North America and Europe.’
- ‘This was due to their appeal as a visual spectacle and because they became economically important as high producers of guano, droppings that the country mined and exported around the world for fertilizer.’
- ‘On islands off of the coasts of Peru and Chile, penguin eggs and guano (dry bird droppings) are collected for local use.’
- ‘Those islanders were forced to work under horrific conditions in the guano mines of Peru.’

- ‘Johnston Island was annexed into the United States as a guano island under the Guano Act of 1856.’
- ‘Here the island dips into a broad, shallow depression where guano was once mined.’
- ‘We sat for ages, just gazing at the Bass Rock, its thick covering of guano making it glisten like a wedding cake in the sun.’
- ‘Whole cliffs of guano, the soluble nitrogen-rich excreta of seabirds, had piled high on a few rainless islands off the shores of Peru.’
- ‘As they'd noted, this area had a somewhat disused look to it, for the floor was covered with a conglomeration of dirt, guano and silt interspersed with crumbling bits of masonry or fallen pillars.’
- ‘He claimed Midway for the U.S., based on the Guano Acts of 1856, which authorized Americans to temporarily occupy uninhabited islands to obtain guano.’
