This plant formerly was found in a wider variety of terrain, but rapid expansion of agriculture appears to have destroyed its habitat in all but the most rugged areas on narrow canyon walls. Given its rarity and extremely rugged, often cliff-faced habitat, it is not surprising that it has been neglected by biologists. This cactus (Espostoa frutescens) is endemic to Ecuador, apparently found only in one arid valley in the whole world. Old Man’s Beard or San Francisco cactus was the reason for our being in Ecuador.

Ralph had already made numerous ground-breaking discoveries, including that most flowers could be identified by their unique echo “fingerprints,” but together he and Merlin would learn much more through close observations and photography in Merlin’s portable photo studio. He and Merlin had agreed to collaborate in preparing an article for National Geographic (Read Blog #2 for the Back Story). thesis on unique adaptations bat-dependent plants have evolved to help echolocating bats find their often highly specialized flowers. These guys had never met before, but they hit it off famously and worked so well together, hunting for flowers on crumbling cliff edges, through thorny thickets, sometimes in a rainstorm, returning always with beautiful flowers–and smiles. Nery volunteered his veterinarian surgical skills, and without anesthesia, took out a half-inch-long spine. The next day, the cactus spine was still bothering Ralph. They brought the flowers back to the studio, worked with Merlin to create a set, helped with the photography and the bats till the wee hours of the morning. While looking for flowers with Nery, Ralph got a cactus spine in his knee, yet he continued his search till sundown. He’s very considerate of others, and he never complains. And the beautiful thing is: it’s contagious. What a concept! So whenever he’s around, there’s lots of laughter. He works extremely hard, but likes to have fun at the same time. Everyone loves Ralph, especially yours truly. And it’s not just because he had an SUV with 4-wheel drive. To say we were overjoyed when Ralph arrived the day after we got stuck in the mud, is an understatement. It is being delivered by the National Lottery Heritage Fund in partnership with Natural England, the Environment Agency and Forestry Commission.No man is worth his salt who is not ready at all times to risk his well-being, to risk his body, to risk his life, in a great cause–Theodore Roosevelt The fund was developed by Defra and its arm's-length bodies. The Merlin Magic Project is funded by the government's Green Recovery Challenge Fund. This will help us to understand whether the degree of heather management in each territory impacts breeding merlin.Īerial image of merlin territory with mapped burns in yellow. To see how heather management has changed over time, we use three images taken approximately 10 years apart between 2001 to 2021. To support our work in the field, we have been using aerial photos to map the size of heather burns and cuts within each merlin territory. Merlin nest among tall heather after chicks have fledged, identified by prey remains. To quantify availability of suitable patches within the breeding territory (1km of the nest) we have measured the vegetation height and composition, and the frequency and size of patches of tall heather (greater than 30cm) along four equally spaced parallel transect lines placed within a 1km radius around the nest.įieldworker taking vegetation measurements along a transect within merlin territories. Having identified 32 nests on grouse moors where merlin bred in 20, we have surveyed the vegetation at nests and in the surrounding area. At the nest we have taken measurements of the heather height and other vegetation present. As merlin prefer to nest in tall heather, we also measure the size of the heather stand (patch) containing the nest. As merlin are specially protected, it is important that they are not disturbed while they are breeding, so we collect these measurements after the breeding season ends. With the merlin gone for the winter, we have been busy in the uplands taking field measurements to understand what makes habitats suitable for nesting merlin.
