The Adult Male

The background colour of a mature pure male jungle fowl is black with various shades of red and yellow on the neck, wings and back.  The main tail feathers are laterally compressed and the lesser sickles are well arranged and obviously shorter than the greater sickles. The mean tail length of the main tail feathers measured from nine newly caught adult males was 17.7 cm and range from 14.3 cm to 19.9 cm. The total number of the main tail feathers in fully feathered male adults is 12, 6 feathers on each side. The number of lesser sickles was found to be 4 on each side. In the typical crossbreds the lesser sickles are longer and many curve downwards to mingle with the greater sickles.  The lateral side of the lesser and greater sickles are metallic black with greenish sheen.  The head of the jungle fowl is relatively small.  The comb is single, well developed but is relatively small, thin and serrated. The comb mean length, from the anterior attachment of the comb to the base of the furthest end of the posterior part, was found to be 7.9 cm and range from 7 9.2 cm. The comb height from the highest point of the serration to the base of the attachment was found to have a mean height of 4.7 cm and with a range of 3.9 cm to 5.1 cm. The total mean number of serrations (including small buds) was 9.6 and range from 6 13.  The lappets and the ear lobes are also well developed but usually smaller than the crossbreds and the face is pinkish red like the comb. The lappets when seen from the anterior views tend to be closer to each other as compared to those of the crossbreds which tend to open rather widely. The mean length of the ear lobe was 2.4 cm with a range of 1.5 cm 3.5 cm and the mean breadth was 2.1 cm ranging from 1.7 cm 3.4 cm. The lappets or wattles had a mean length of 3 cm and range from 3 cm 3.4 cm and the breadth had a mean of 2.9 cm and a range from 2.6 cm 3.7 cm.

The comb becomes bluish in newly caught birds kept in captivity.  The ear lobes I found vary in colour and size.  They can be the size of a 10 cents or 20 cents Malaysian coin, completely red, completely white or whitish with reddish tinge, the latter colour being the most common.  The colour of the eyes surrounding the black retina in most birds has a reddish tinge unlike most crossbreds with whitish or yellowish colour.

The wings are well developed and longer than the whole length of the body including the tail. The total mean length of the wing spread fully stretched from the furthest tip of 1 wing to the furthest tip of the other wing was 72 cm and range from 63 76 cm. The breadth mean was 21.9 cm and range from 20 cm 23.6 cm. The front shoulder plumage is greenish black, the wing bow is dark red, wing converts are black with slight reddish lines in some feathers, the secondary flight feathers are half black and half brownish yellow and primary flight feathers are black with short yellowish line in the center. The number of the first small feathers of the wing is three (3) on each side, the number of primary flight feathers range from 9 11 while the secondary flight feathers range from 12 -14 on each side.

The neck hackles tend to be reddish orange from the head and yellowish red downwards towards the back.  The colour of the back is dark red.The body of the jungle fowl is relatively slim and boat shaped and the legs of the fowl are relatively slimmer with a smooth texture. The mean body length measured from the tip of the beak (fully stretched neck) to the tip of the oil gland was 36.4 cm and range  from 35 cm 38.1 cm. The mean length of the leg (shank) was 8.7 cm and range from 8.1 cm 9.4 cm. The diameter of the center of the shank had a mean of 3.5 cm and range from 3.4 cm 3.9 cm. We have never come across any adult bird weighing more than 11/2 kilogram and because of this plus its well developed flight feathers the jungle fowl is a strong flier as compared to the crossbreds. The mean weight of newly trapped adult male jungle fowl was 1023.8 grams and the range was 800.3grams - 1220grams. The colour of the shank is slaty blue whereas the crossbreds have either bluish black, greenish or yellowish colour. The spur is triangular in shape and tends to curve upwards in older birds. The mean length of the spur in the adult male was found to be 2.2 cm and range from 1.9 cm 3.2 cm.

The crossbred males that are usually kept by villagers are either larger or smaller than the pure jungle fowls.  The head is usually larger and the combs and lappets are usually bigger, rougher and thicker.  The breast feathers may contain brownish or yellowish specks on the black background colour previously described.  One important difference between a jungle fowl and the crossbreds is in the crow.  The last note of the crossbred may be either too high pitch ending abruptly like the pure bird or it ends for a longer duration than the purebreds.  The crow of the crossbreds is noticeably coarser than the pure jungle fowls.  However, those crossbreds with a strong bantam origin have a finer sharp crow.

I have crossed pure male jungle fowls with crossbred females and the products of these crosses are difficult to distinguish from the pure birds.  However, a few points may indicate that the bird is a cross.  For example, the boat shape body is slightly off shape in the crosses and the slaty blue colour of the tarsus may be either darker or having a greenish tinge.  Furthermore these crosses are relatively tame and can be set free and kept just like village birds.

Figure 29: This is the abnormal colored male red jungle fowl with whitish neck hackles caught from the wild. This type of jungle fowl must be a progeny of crosses between the pure jungle fowl and village chickens.

Figure 30: This is the golden type red jungle fowl occasionally caught not far from villagers. Note the golden flight feathers are more in numbers as compared to the typical pure jungle fowl. This type must have descended from a cross between the male jungle fowl and village chicken.
