I found a sparrow chick on the pavement – what now? This is a question many people ask themselves, especially between May and July when the sparrow breeding season is at its peak. Before you take any action, you need to know that not every young bird requires rescuing. This guide will take you through all the stages: from recognising the situation, through emergency feeding, to contacting professionals.
If you're standing over a chick and need some quick advice, here are the key points:
A typical situation looks like this: a May or June morning, you're walking along the pavement and suddenly you see a tiny, helpless creature under the window of a tenement building. Sparrow nests in building crevices, under roofs, or in nesting boxes can fall out due to storms, predator attacks, or renovations.
Identifying young birds of this species is not difficult:
Chicks become fledglings after about two weeks, leaving the nest even though they cannot yet fly well. This is a natural stage of development. Sparrow fledglings are very sociable and noisy – they hop, peep, and actively react to their surroundings.
| Feature | Chick | Woodlouse |
| Feathers | None or minimal | Full plumage |
| Eyes | Closed or newly opened | Fully open |
| Reaction | It lies there limply, trembling | Unique touch, it bounces |
| Parents | Feeding in the nest | They feed from a distance |
Chicks of sparrows that have left the nest may be cared for by their parents, who continue to feed them and teach them independence, so they do not always require human intervention. Observe from cover for 20-30 minutes to see if adult sparrows return – look for birds carrying insects in their beaks.
Intervene immediately when:
Intervention is necessary when a chick is unfledged, unable to move or fly, meaning it requires immediate assistance.
Important: The myth of parents rejecting their young because of human scent is completely false. Birds do not rely on smell – their parental instinct is based on the chick's sounds and visual cues.
Before you start feeding a baby sparrow at home, you need to understand what it eats in the wild. This knowledge will help you choose the right diet and avoid serious health problems.
Adult birds, despite their granivorous lifestyle, switch to insectivory during the breeding season. They collect aphids, small caterpillars, spiders, midges and larvae in meadows, lawns and gardens. In the first weeks of their lives, sparrow chicks are fed almost exclusively on animal matter, mainly insects such as aphids, caterpillars and spiders, which provide the essential protein for their growth.
Protein accounts for 70–90% of the nutritional value during the first 10 days of life. This is crucial for the development of muscles, bones and feathers. Parents feed their chicks up to several dozen times an hour – under favourable conditions, this can amount to 50–100 returns to the nest per day.
Seeds They are only introduced after 10–12 days of age. Before this, the digestive tract of young chicks is not adapted to digesting solid food. A protein deficiency in the first few weeks causes rickets, weakness and mortality rates of up to 80% in poor breeding seasons.
This section is for situations where there is no realistic chance of returning a chick to its nest or getting it quickly to a rescue centre. What should chicks be fed in these circumstances?
The optimal temperature for sparrow chicks in the first weeks of life should be between 30 and 35°C to prevent chilling. Never feed a chilled bird – its body is unable to digest food.
How to warm a chick:
After 15-30 minutes of thermal stabilisation, you can proceed with feeding.
Sparrow chicks require a diet rich in soft insects, earthworms, and larvae, which are easily digestible and provide protein and other key nutrients in their first few weeks of life.
Recommended foods
In the diet of sparrow chicks, earthworms and larvae, such as mealworms, are important sources of protein that support their growth and energy.
For unfledged chicks (1-5 days):
For older chicks (6-12 days):
If you don't have access to feeder insects:
Please note: This is only a solution for the first few hours. The lack of a complete nutritional profile causes diarrhoea after 24-48 hours.
Many human food products may seem suitable, but they are dangerous for chicks. Statistics from rehabilitation centres show that 60% fatal mistakes are caused by an inappropriate diet in the first 24 hours.
Chicks should not be given bread, milk, meat, cold cuts, or dog/cat food.
| Product | Why dangerous |
| Bread | Swells in the crop, blocks digestion (death in 12-24h) |
| Milk and dairy | Lactase deficiency, fermentation, diarrhoea |
| Raw grains, rice, groats | They damage the digestive tract |
| Salted nuts, cured meats | They damage the kidneys (hypernatraemia) |
| Too many fruits | They acidify the stomach |
| Avocado | Contains the toxin (persin) |
Do not give water from a large syringe or bottle into the beak. This risks choking and pneumonia, which can kill a chick in 1-2 days. Young birds get most of their water from moist food. Water can be given drop by drop with a syringe or pipette, but only if there are clear signs of dehydration.
Regardless of the situation, do not experiment with human medications or vitamins. Paracetamol is toxic to a bird's liver.
The feeding schedule depends on their age. We feed a naked chick differently from an active, feathered fledgling.
In the first few weeks of life, chicks require regular feeding every 2-3 hours, which means intensive care. In more detail:
Feeding takes place from early dawn (around 5-6 am) to dusk (9-10 pm in summer). At night, birds in the wild are not fed – the chick rests at a slightly lower temperature (around 25°C).
When feeding chicks, food should be given directly into their beaks:
Assess the situation before each instance. If the uterus is hard, contact a specialist.
Even the best dietary solution won't help if the chick is in unsuitable conditions. You must ensure it has the right temperature, quietness, and safety for proper development.
Chicks should have access to suitable nesting materials and a space that provides them with comfort and safety:
| Stage of development | Temperature | Heat source |
| Naked chick | 30-34°C | Heating mat for the 50% box |
| Partially feathered | 28-30°C | Hot water bottle every 3 hours |
| Woodlouse | 25°C | Room temperature |
The humidity in the environment around sparrow chicks should be maintained at 50–70%, which is crucial for their health. Dry air can dry out their airways.
Warning: Do not overheat the chick – temperatures above 35°C cause heatstroke.
The box should be placed in a quiet location.
Noise raises cortisol levels, which inhibits growth and weakens immunity.
Observe chick droppings as an indicator of its health:
Rearing a sparrow chick in a flat is very difficult. The mortality rate in home care without experience is as high as 50–80%, whilst in professional centres it falls to 20–40%.
If you are certain that a chick needs help, you can contact a bird sanctuary or a veterinarian for professional assistance:
Professional help means:
Within the first hour of finding the bird, call for advice. Even a short phone consultation can save the fledgling from nutritional mistakes and increase its chances of survival.
Yes – if you know where the nest is and can reach it safely, gently placing the chick back in the nest is the best course of action. The parents will not abandon their young because of the smell of humans. Birds recognise their parents by their calls, not by their smell. The risk of rejection is much lower than the risk of the chick being raised by someone without experience. In 80% cases, the adult birds return within 30 minutes.
Naked chicks require very frequent feeding, and even 2-4 hours without food when chilled can be critical (hypoglycaemia). With older fledglings, the safety margin is slightly larger (6-12 hours), but any help should be planned as soon as possible, ideally the same day. Don't delay – time is life.
A low box is better at the beginning, as it limits the risk of falls and injuries – a fall from a height of more than 20 cm can cause fractures. A typical tall cage is not suitable for naked chicks and young fledglings. A cage may only be useful in the final stage, when the bird is fully feathered, can move independently, and is learning to fly. Then, ensure safe equipment without bars that could cause entanglement.
Chicks leave the nest approximately 14-16 days after hatching, and their diet differs from that of adult birds. For the next 1-2 weeks, they remain under parental care as fledglings. Healthy development and full independence occur around 25-30 days of age. In domestic conditions, the bird should be released when it can confidently fly at least 50 metres, independently consumes a varied diet, and responds appropriately to environmental stimuli.
The house sparrow is a wild species protected under the Nature Conservation Act of 2004 (Art. 52). Its prolonged keeping without appropriate permits is generally prohibited in Poland, carrying a fine of up to PLN 5,000. The aim of any intervention should be the return of a healthy, fully functioning bird to the wild, preferably under the care of specialists from a rehabilitation centre. Permanent keeping deprives the bird of an independent life and the natural behaviours of bird species.
Remember: Finding a baby sparrow is a responsibility. Act quickly, but think it through. The general guidelines from this article will help you through the first critical hours, but professional assistance will always yield the best results. Save the number of your local wildlife rescue centre in your phone – it might come in handy not only for you but for anyone who encounters a bird in need of help.
