This picture is of an elaborate burrow system (Calhoun 1963).
Rat burrows are made up of multiple parts. These include the entrance, the tunnels, cavities and the nest. Burrows are often started by a pregnant female, where a single burrow and nest is created. After this tunnel is built others are made including bolt holes and food caches.
A study of what parts made up burrows was carried out. 44 burrows were studied. The average amounts are displayed below.
tunnel segments: 16
adult rats: 5.5
Rats have complex social behaviour and either live in small colonies with a dominant male or when population densities are high males no longer defend female burrows. Instead, when a female comes into heat a group of males rushes her and mates with her sequentially, with little or no competition between themselves. Males may mate with multiple estrus females this way, and females mate with multiple males. This mating system is polygynandrous. At high densities, Norway rats are therefore despotic and polygynandrous.
