On the evening of March 18, as it was growing dark, I went to the window, not knowing what was drawing me. Next to the house stood a shadow, ghost-like, shrunken, at one with the dusk, almost translucent, and I recognized The Girl with the Broken Foot.

I walked out into the falling wet snow, slowly approaching her, and she allowed me to come close. Nine months old, she was the size of a fawn half that age. Starkly emaciated, her body seemed to be collapsing inward, her head held low. Literal hunger and a deeper starvation were palpable. She bore the haunted look of terminal solitude seen in souls driven to the margins of society, among the liv-ing, yet apart. She seemed so frail that I couldn’t imagine she would live more than another day or two.

Going inside and returning with a bowl of apples, I cut them into pieces and placed a few on the ground between us. She was raven-ously hungry and I gave her a few more apples, and still more, until she had eaten a total of eight. After she had finished eating, she stayed with me. We stood about a foot apart. She showed no fear of me, a fact which I would later come to recognize as meaningful. The moment had the compelling quality which has been present at the onset of many enduring connections in my life, of being un-bound by linear time.

“I am watching over you,” I said softly. “If you come here, I will take care of you. You are not alone.”

It was fully dark when we parted, having been together for an hour. I expected that she would recede into the woods, yet the next morning she was sleeping against the house, directly beneath the window closest to where I sit all day to work. Save for the wall separating us, she could not have gotten any closer to me.

When I went around to the front of the house, she struggled to her feet and approached. In the morning light, I was better able to assess the state of her health. Months of solitary survival had taken a severe toll. Her body seemed hollowed, her ribs and pelvis sharply visible beneath her skin, and it felt a miracle that she was alive. On her right flank was a hemispherical mass the size of a cantaloupe, which I took to be a tumor, yet it had an open, running wound at its center, which she periodically craned her neck to lick. Her eyes were running and had congealed masses at their inner corners.

I bent to get a look at her injured foot. From not being walked on, the backward-facing cloven hoof had grown to an abnormal length and was curling upward. The wrist, which unnaturally bore her weight, had a flattened forward surface, an oval about two inches across, worn raw, without hair or skin, only pale pink–grey flesh, which, at its center, appeared to have been further abraded to the bone. Her right front foot, forced to compensate, was splayed and rockered, her right scapula protruded, and her front quarters were substantially lower than her hips.

I again placed apple pieces on the ground between us. I spoke very gently to her, saying, “You are the best one of all the deer. You are the most beautiful. You are good.” I continued to talk to her while she ate her apples, and when she had taken all she could, she returned to her resting spot under the window. I went inside to work, keeping periodic watch, pleased that she seemed to have claimed a place. But in a few minutes, from around the corner of the house came the twins, followed by their mother who immediately and ag-gressively charged at her. The Girl with the Broken Foot lurched upright and hobbled down the embankment, across the road and into the woods.

She was once again alone, but a step had been taken. Since the previous evening, things had changed. Even before her second feed-ing she had recognized me on sight. She had approached and had again allowed me near.

Although I had seen her fewer than half a dozen times in the preceding months, from the night of our first connection, she began to come to the house every day. She slowly gained strength and I would watch for her and thrill to the sight of her slow approach. It was our private time. We stood together, and I placed her food on the ground between us. After she ate, she would stare into my eyes for long periods, seemingly entranced. I told her stories. I sang softly to her. I told her she was my beauty.

So began our journey, and one of the greatest loves I have ever known.

Real-life vampire birds hunt and drink blood in remote Ecuador

18 October 2026 at 13:04

When zoology professor Daniel Baldassarre traveled to the remote Galápagos Islands of Wolf and Darwin with two other researchers, getting there proved quite a challenge. With no beaches to land a boat on, they had to approach the islands’ cliffs in a small dinghy and wait for a lull in the waves before jumping onto sharp, black lava rocks.

But their efforts paid off. On that trip, they saw a bird that very few people have ever set eyes on in the wild: the vampire ground finch. These finches are only found on Wolf and Darwin, and feed on the blood of much larger birds called Nazca boobies that also live on the islands. 

Up close, Baldassarre and his colleagues noted the vampire finches’ blood-stained bills and their throats visibly engorged with blood. They also saw them in action. 

“We observed scores of vampire finches clamouring all over the backs, tails, and wings of boobies, opening up substantial wounds with their sharp beaks, and drinking their fill of blood,” they wrote in an article for The Conversation. 

Why only some birds drink blood

“Blood is a notoriously difficult food source to process and extract nutrients from, which probably partly explains why so few animals have evolved to feed on it,” Baldassarre tells Popular Science. He suspects that on these islands where freshwater is extremely rare, blood might serve as a water source for the finches.

It’s not the only component of the vampire finches’ diet, however. Based on unpublished data collected by Baldassarre and his colleagues, blood makes up about one-tenth of the vampire finches’ diet. 

“These finches are quite opportunistic, so they will eat just about anything they can find,” Baldassarre says. “We observed them feeding on everything from seeds to insects to broken seabird eggs.”

One theory is that vampire finches rely more on blood feeding in periods of extreme drought, when other resources are scarce. But more research is needed to see if this idea holds up in practice.

How this strange behavior evolved

Vampire finches weren’t always vampires, scientists think. The relationship between vampire finches and boobies probably started off with the finches eating parasites found on the skin and feathers of the boobies. This would have been mutually beneficial because it provided a cleaning service for the boobies and food for the finches.

But at some point in evolutionary history, in the process of picking off parasites, the finches started to create lesions on the boobies’ skin, and eventually began feeding on their blood.

Over time, their bills became more scalpel-like, perfect for making skin incisions. Their digestive system also changed. When Baldassarre and his colleagues studied the microbes found in vampire finches’ guts, they found that their gut microbiome was very different from that of other, non-blood-consuming finches on the Galápagos Islands, something they attribute to their unique diet. 

Until recently, vampire finches were considered a subspecies of the sharp-beaked ground finch (Geospiza difficilis). 

“But they have now been designated as their own species [Geospiza septentrionalis] because of the differences they have evolved because of blood feeding,” Baldassarre notes.

How the boobies cope 

Baldassarre and his colleagues have seen vampire finches gang up on and kill nestling boobies,“but that was quite rare,” he points out. 

“In most cases, the finches seem to inflict just enough damage to break the skin and extract some blood, but not too much to harm the boobies significantly.” This is similar to many parasite-host relationships, such as fleas, ticks, and mosquitoes on mammals. “You can kind of think of the vampire finches as giant mosquitoes,” Baldassarre says.

As seen in a segment on vampire finches in David Attenborough’s documentary A Perfect Planet, the boobies seem to tolerate the vampire finches rather than chasing them away. There are likely a few reasons for this, Baldassarre says. 

“For one, as in large animals being bitten by mosquitoes, often the damage is minimal and not noticeable, so it doesn’t elicit a strong reaction. Also, the boobies sometimes have a vested interest in staying put and guarding their spot in the colony, or perhaps nest or nestlings, so may not want to fly away. Finally, the finches seem to target hard-to-reach areas on the boobies like the base of tail feathers, so it’s likely difficult for the boobies to deter them.”

I, for one, was feeling very sorry for the boobies being constantly hounded by these small vampire birds. Until I learnt that Nazca boobies practice something called “obligate siblicide,” which essentially means that the first-hatched chick routinely attacks and kills its younger sibling. It’s a harsh, bird-eat-bird world in the Galápagos Islands.
