As part of bird monitoring activities in the working area of the Yogyakarta Natural Resources Conservation Agency (Balai Konservasi Sumber Daya Alam Yogyakarta), particularly in Gunungkidul Regency, officials unintentionally documented the presence of a Shining Bronze-cuckoo, Chalcites lucidus (Gmelin, 1788). We photographed a single individual on 21 June 2024 that we initially misidentified as a Horsfield's Bronze-cuckoo, Chalcites basalis
A recent study by Parmar & Kaiser (2024) linked unusual morphs in Russell’s Vipers and Wolfsnakes to the spark/spark genotype mutation. We report a similar aberrant pattern for the first time in a sea snake observed in India (Bharuch District, Gujarat). During a marine reptile survey on January 26, 2019, near Aliabet, Bharuch District, in the Gulf of Khambhat (21.5958°N, 72.4408°E), fishermen caught 24 Annulated Sea Snakes (Hydrophis cyanocinctus) and one Little Filesnake (Acrochordus granulatus). One sea snake had an unusual pattern, differing from all other sea snakes. This individual measured 1030 mm in SVL with a tail length of 110 mm.

Pelung chicken, Gallus gallus gallus (Linnaeus, 1758), is an Indonesian endemic species of poultry from Cianjur, West Java. The characteristics of the Pelung chicken are that it has (1) a distinctive voice of long duration, (2) relatively fast growth, and a large physical shape, (3) good meat quality, which can be seen from the improvement in muscle mass and strength, and (4) growth performance in line with high testosterone levels. This species has been defined under the 2918/kpts OT.140/6/2011 decree issued by the Ministry of Agriculture as a native Indonesian free-range chicken that is to be protected and conserved, as well as a national asset. The chicken is reportedly threatened due to decreased population size.

Unusual nest construction by cinereous tit (Parus cinereus) in an artificial nest box
M. Bilaskar* *Corresponding author. E-mail: rishi08sep@gmail.com
The cinereous tit, Parus cinereus Vieillot, 1818 is the descendant subspecies of the great tit (Parus major), which it was included with until it was recognised as a separate subspecies. The nesting behaviour of the cinereous tit is characterized by its preference for cavity nesting. These birds typically choose tree hollows, crevices in rocks, or even man-made structures such as walls and pipes for nesting. During the breeding season, which generally occurs from March to July, the female cinereous tit plays a dominant role in nest construction. In urban settings, they may use synthetic materials such as pieces of cloth or plastic. The typical clutch size ranges from 4 to 8 eggs, with incubation lasting about 12 to 14 days. Both parents are involved in feeding the chicks, with the fledging period extending for approximately 16 to 20 days.

The preservation of fish sperm is still an area of research that is being developed. This technology has emerged as a widely used method for implementing artificial fertilization of species of economic significance, endangered species, or animals with unique genotypes. During the preservation process, fish sperm are exposed to significant temperature decline (cold stress). Cold stress commonly leads to the production of reactive oxygen species (ROS). Cold stress caused by preservation has been reported as a major contributing factor to inducing apoptosis in sperm.
