Many bird feeders say that the method of harvesting bird nest is an art, balancing the increase in the number of bird nest and income stabilization for farmers. Harvesting bird nest requires a lot of techniques because if harvesting the wrong time or the wrong way will result in low productivity and can affect the quality of the nest. Harvesting oats should follow certain rules:
● Harvesting at the time of the bird's rest will disturb the bird's life. The ideal time to harvest is 9:00 to 15:00 when birds go for food.
● The time of harvest is also the time to check and remove the harmful factors for birds.
● In order for the nest to not be broken, before the water must be sprayed around the nest attached to the bar. Then use thin knife to harvest.
Currently there are 3 methods used to exploit nest:
1. Harvest nest before bird lays egg
The method of harvesting nest before bird lay egg is popular. The reason that this method of harvesting oats is preferred is because the nest will be clean and less amount of dust, feather or not. At the same time, due to the short building time, if the nest is found lost, the bird will immediately rebuild the new nest.
● Advantage is that the oats harvested by this method will be very clean, very little feather, dust which help it easier to clean and sell the nests.
● The downside to this harvesting method is that harvested nest will be thinner and lighter due to shorter nesting times. In particular, parents must immediately rush to build a new nest to lay egg, so it will greatly affect the health of the parent birds due to produce a large amount of saliva to build new and continuously. Parent bird’s exhaustion to make the new nest will lead to bad effect of the nursing process also, the birds were weaker and more likely to die. As a result, it affects to the increasement of total number of bird in the house.
2. Harvest the nest when the bird lay 2 eggs
The method of harvesting when nest has spawned two eggs in the team to help maximize the harvest of bird nest up to 4 times a year. This method is rarely applied by the bird nest because it reduces the number of young birds in the nest very fast because there are no young birds to maintain the total number of bird, parents bird will go to other habitats to find better place. And above all, it reflects the human ethic in farming technique.
● The advantage of this method of harvesting oats is that the nest is more complete in terms of structure of the nest is also thicker than above method.
● The downside is that the number of birds nest in the nest will be reduced because there are no eggs hatched into the birds.
3. Harvest swift nest after the bird nest removed
This method of harvesting is applied by Yen Thanh and most of the harvesters because of its ethic. This method helps the nest swiftly increase the number of bird quickly, the nest harvesters follow this method is considered to have deeply consideration in the bird habitat conservation.
● The advantage of this method of harvesting is that the number of bird in the house will increase quickly because it contains large numbers of young birds and they will continue to build new nests.
● The downside is that nest harvested it is very dirty because it contains many feathers, egg shells, bird feed and other impurities. Consumers have to work harder to clean the nest.
Epilogue
Breeding bird is a profound ethic, helping to preserve and develop the number of swiftlet birds. Protecting and developing the number of bird nest is also the key to a successful bird nest.
