A study has reported that The crow Waits to get its favorite food whether a rival bird is present or not.
However, according to research by Anglia Ruskin and Cambridge universities, another the birds In the presence of , Nile kanthas will settle for the less preferred food rather than wait for the preferred food and take the risk of being deprived of it.
Both types of birds have the self-restraint ability to delay gratification while waiting for something better, the study’s authors say.
Rachel Miller, co-author of the study and senior lecturer in biology at Anglia Ruskin University, said that Nile sparrows are less sociable than crows and tend to hide food so they can eat it later to survive. .
He said that this is probably the reason why Nile kanthas seem to change their strategy and choose to reach for their less preferred but more readily available food when another bird is present.
The researchers examined the behavior of six New Caledonian crows and five Eurasian Nile-throated birds when they were presented with two types of food on a rotating tray. One diet was of better quality and the other of poorer quality.
The high-quality food for Neelkunth was the insect found in the diet and the low-quality food was bread, while the favorite food for crows was meat and the least favorite food was apple.
The birds had to scavenge food from the bottom of transparent plastic bowls.
Each bird was tested separately. They watched as both types of food were placed in the rotating tray.
Meanwhile another bird, though a direct competitor and not a competitor, remained in an adjacent box.
Just before the less preferred food choice became available on the rotating tray, the door between the boxes was opened, allowing access to the other bird.
The bird being tested could then choose the immediately available food or wait 15 seconds for the preferred food.
The study found that each Nile kantha chose high-quality delayed food (meal bugs) when alone but chose readily available food (bread) when a rival or competing bird was present.
In contrast, each crow remained in place and waited for the high-quality delayed food (meat) rather than the immediately available low-preferred option (apple) in all three test conditions.

“Delayed preferred food, in this case the refusal of a readily available small meal and waiting for something better, demonstrates self-control,” Dr. Miller said.
According to Miller: ‘We also used this rotating tray for a comparative assessment of self-control in young children.
“Both Eurasian Nile Crows and New Caledonian Crows have a high waiting capacity to enjoy better food and we expected that both species would prefer high-quality and preferred food in the presence of a solitary and possibly non-competing bird. Will wait, but will choose low-quality, readily available food when a competitor is present because waiting may lead to loss of food.
“Interestingly, we found that Nile ravens were highly flexible in their late-preferred food behavior and that this behavior was completely influenced by the presence of other birds, but crows consistently chose the better and delayed food, the reward. What, despite the fact that there were rival birds.
‘These findings add to our understanding of the factors influencing self-control and delayed gratification behavior in animals, which may be related to a particular breed’s levels of social tolerance and competition. .
‘New Caledonian crows are more sociable and tolerant of others than Eurasian Nile ravens and although both hide food for later consumption, Nile ravens rely more on this strategy for survival.
‘This may explain why, when competing birds were present, large numbers of territorial Nile kanthas changed their strategy, choosing less preferred food that was readily available to avoid being completely deprived of food. ‘

The Patient Crow: A Study on Self-Restraint and Food Choice in Birds
In a fascinating study, researchers from Anglia Ruskin and Cambridge universities have discovered that crows will wait for their favorite food, even when a rival bird is present, whereas Nile kanthas will settle for a less preferred food option in the same situation. This study sheds light on the self-restraint abilities of birds and highlights the differences in their food choice strategies.
Delayed Gratification in Birds
The study, which involved observing the behavior of six New Caledonian crows and five Eurasian Nile-throated birds, found that both species have the ability to delay gratification while waiting for a better food option. However, when a rival bird was present, the Nile kanthas changed their strategy and chose the less preferred food, whereas the crows remained patient and waited for their favorite food.
The Experiment
The researchers presented the birds with two types of food on a rotating tray: a high-quality food and a low-quality food. For the Nile kanthas, the high-quality food was insect-based, while the low-quality food was bread. For the crows, the high-quality food was meat, and the low-quality food was apple. The birds were required to scavenge for food from the bottom of transparent plastic bowls.
In the experiment, each bird was tested separately, and the researchers observed their behavior when a rival bird was either present or absent. The results showed that the Nile kanthas chose the high-quality delayed food when alone, but opted for the readily available low-quality food when a rival bird was present. In contrast, the crows waited for the high-quality delayed food in all three test conditions, regardless of the presence of a rival bird.
Self-Control in Birds
Dr. Rachel Miller, co-author of the study, explained that the ability to delay gratification in order to obtain a better food option demonstrates self-control. “Both Eurasian Nile Crows and New Caledonian Crows have a high waiting capacity to enjoy better food,” Dr. Miller said. “We expected that both species would prefer high-quality and preferred food in the presence of a solitary and possibly non-competing bird, but would choose low-quality, readily available food when a competitor is present because waiting may lead to loss of food.”
Social Tolerance and Competition
The study’s findings suggest that the presence of rival birds influences the food choice strategy of Nile kanthas, but not crows. Dr. Miller noted that New Caledonian crows are more sociable and tolerant of others than Eurasian Nile ravens, which may explain why the latter changed their strategy in the presence of competing birds. “Nile ravens rely more on hiding food for later consumption as a survival strategy, which may explain why they chose the less preferred food when competing birds were present,” Dr. Miller explained.
Implications for Understanding Animal Behavior
This study provides new insights into the factors that influence self-control and delayed gratification behavior in animals. The researchers suggest that social tolerance and competition may play a significant role in shaping the food choice strategies of different species. “These findings add to our understanding of the complexity of animal behavior and highlight the importance of considering social and environmental factors in our studies,” Dr. Miller concluded.
the patient crow’s ability to wait for its favorite food, even in the presence of rival birds, is a testament to its self-restraint and strategic thinking. This study not only sheds light on the fascinating world of bird behavior but also provides valuable insights into the evolutionary pressures that shape their behavior.

The Patience of Crows: A Study on Self-Restraint and Delayed Gratification in Birds
When it comes to waiting for food, birds exhibit varying degrees of self-restraint and delayed gratification. A recent study by Anglia Ruskin and Cambridge universities has shed light on the differing behaviors of crows and Eurasian Nile sparrows in the presence of rival birds.
Crows Wait Patiently for Preferred Food
The study found that crows will wait to obtain their preferred food, even when a rival bird is present. In contrast, Eurasian Nile sparrows will settle for a less-preferred food option when another bird is nearby, rather than waiting for their preferred option and risking deprivation.
Self-Restraint in Birds
Both types of birds possess the ability to delay gratification, a trait known as self-restraint. This ability allows them to wait for something better rather than opting for an immediate, but less desirable, option.
Nile Sparrows and Social Behavior
Researchers suggest that Nile sparrows’ behavior may be influenced by their less sociable nature and tendency to hide food for later consumption. This strategy is necessary for their survival, as they rely on cached food to sustain themselves. In the presence of a rival bird, Nile sparrows may choose a less-preferred food option to avoid losing their preferred food to a competitor.
Experimental Design
The study involved presenting six New Caledonian crows and five Eurasian Nile-throated birds with two types of food on a rotating tray. The high-quality food option was insects for the Nile sparrows, and meat for the crows, while the low-quality option was bread for the Nile sparrows and apple for the crows.
Each bird was tested separately, and the researchers observed their behavior when alone and when a rival bird was present. The results showed that Nile sparrows would choose the readily available, less-preferred food when a rival bird was present, whereas crows consistently chose the higher-quality, delayed food option, regardless of the presence of a rival.
Delayed Gratification and Social Tolerance
The study’s findings contribute to our understanding of the factors influencing self-control and delayed gratification in animals. The results suggest that social tolerance and competition levels may play a role in shaping an animal’s behavior, with more sociable species, like New Caledonian crows, exhibiting greater patience and self-restraint.
Conclusion
this study provides insight into the unique behaviors of crows and Eurasian Nile sparrows when it comes to waiting for food. While crows exhibit remarkable patience and self-restraint, Nile sparrows adapt their strategy to their environment, prioritizing immediate availability over preferred food options when rival birds are present. These findings have implications for our understanding of animal behavior and the factors that influence self-control and delayed gratification.
