If you’re a bird-watching enthusiast and had the chance to observe a bird nest carefully, you may be wondering “Why Do Birds Consume Their Children’ Poop?”
Shortly after the adult feeds the nestling, the baby turns its rear end to the mother and produces a strange white sac, which the mother grabs with its beak and then swallows. Sounds gross, right?! So why don’t adult birds even flinch while ingesting these?
The white sacs baby birds release right after eating are called fecal sacs. Some adult birds choose to consume the fecal sacs because they are, in fact, highly nutritious for them. They may also eat them to avoid leaving the nest.
If you believe that’s unusual, wait till you end up checking out the short article! You will uncover some jaw-dropping information regarding an infant bird’s pooping actions! Although numerous facets of this actions will certainly appear gross, they’ll make you appreciate birds even more than ever before!
Why Do Birds Consume Their Children’ Poop?
Infant bird poop need to constantly be eliminated from the nest. Things is, some birds select to do away with it by consuming it due to the fact that it’s very nourishing.
Throughout the nesting period, grown-up birds are rather stressed out and commonly do not have time to look after themselves and consume as necessary, so they make the most of their children’ poop. It has actually been confirmed that women take in infant poop more frequently than men, as their food consumption is commonly much less nourishing.
Furthermore, moms and dads might select to consume their children’ fecal cavities to stay clear of leaving them alone in the nest.
However just what does infant bird poop include that triggers grown-up birds to consume it? Infant bird poop is, actually, called a fecal cavity due to the fact that it does not include feces just. The poop is in fact bordered by a white mucous membrane layer with a dark end.
This membrane layer is of outstanding assistance to stay clear of the nest from obtaining unclean and, consequently, aids moms and dads stay clear of the buildup of pathogenic microbes. Furthermore, the elimination of these fecal cavities stops killers from discovering the nest.
Reasons Birds Consume Offspring Feces
Here are some of the key reasons adult birds engage in fecal matter consumption of their young’s waste:
- Bird nutrition: Fecal sacs contain undigested food remains and nutrients the parents can utilize when food is scarce during nesting season. “Fecal sacs from nestlings were full of invertebrate remains and grain” (Smithsonian).
- Bird diet supplementation: Consuming offspring feces allows parent birds to supplement their own nutrition, which often suffers during stressful nesting periods. “Adults take advantage of the nutrients and energy stored in the fecal sacs” (Audobon).
- Avian waste management: Eating fecal sacs keeps the nest clean and limits pathogenic bacteria that could sicken hatchlings if allowed to accumulate. The mucous coating “helps avoid accumulation of pathogenic microbes” (Auk).
- Predator avoidance: Removing and consuming fecal sacs helps mask nest scent and prevents predators from finding nest locations. “Removal of fecal sacs prevents predators from finding the nest” (BioOne).
- Reduced nest departures: Consuming offspring feces means less time spent away from vulnerable hatchlings. “May minimize the time spent away from the nest” (Wiley).

Examples of Birds That Consume Offspring Feces
The scientific reasoning behind this avian digestion process is fascinating yet complex. While it may seem unhygienic to humans, bird parenting habits have adapted to make use of all available nutrition sources to raise young. This bird behavior is just one remarkable example of the lengths some species go to in order to successfully nurture offspring.
Why Are Fecal Cavities Nutritious?
As discussed, some bird moms and dads select to consume the fecal cavities as opposed to tossing them away. Researchers think this takes place due to the fact that infant fecal cavities are very nourishing.
A study concentrated on taking a look at 173 feces coming from corn pennant nestlings ( Emberiza calandra) revealed they were full of invertebrate remains and grain grains.
This sensation is much more usual in altricial young that are birthed rather untaught, and their digestive system systems can not refine all the food, and consequently the fecal cavities include remains of what the children are fed. Subsequently, the moms and dads can gain from the nutrients and power kept in the fecal cavities.
Once the children grow, nevertheless, a lot of moms and dads quit consuming their fecal cavities, as their digestion system ends up being significantly more powerful and consequently, efficient in absorbing food correctly. As a matter of fact, when they’re fully grown adequate to fledge, infant birds quit creating fecal cavities.
A study on mockingbirds revealed that the moms and dads quit consuming their children’ fecal cavities once the young were just 6 days old. Hereafter, the grownups lugged the fecal cavities far from the nest. Robins possibly consume their children’ poop just throughout the very first couple of days after hatching out, as well.
Currently you’re possibly asking yourself why the moms and dads aren’t impacted by the germs in the poop? If it threatens to leave the fecal cavities in the nest, why is it not unsafe for the moms and dads to consume it?
That’s where the white mucous membrane layer plays its duty. Researchers suggest that it secures the bird’s skin and plumes from germs. Once it gets to the digestive tract, the bird’s digestion system can deal with the germs well.
Poop Consuming – A Safety Habits
As discussed, an additional factor for moms and dads to consume their children’ poop is to stay clear of leaving the young neglected. If both the man and the women look after their young, this might not be an issue, as they can trade responsibilities.
On the various other hand, so one moms and dad supplies adult treatment, it would possibly do its ideal to stay clear of leaving its youngsters alone, and consuming their poop might minimize the moment invested far from the nest.
Why Do Infant Birds Consume After That Poop Right After?
Studies have actually revealed that infant birds poop right after consuming since that’s what their impulses inform them to do to stay clear of poop accumulating in the nest.
Researchers observed 159 nests of 8 bird types for greater than 400 hours and wrapped up that nestlings’ defecation times depend instead on feeding times than on digestive tract handling times.
Thus, the nestlings researchers observed pooped right after being fed due to the fact that the moms and dads existed to cleanse the poop.
Upon these monitorings, researchers suggested that nestlings have a solid plasticity in defecation time as they can modify the entire physical procedure to make sure that defecation happens when moms and dads are about. Also if the moms and dads feed their nestlings at various times, they still poop just after consuming. Isn’t this interesting?!
