roving room

the two pictures below is taken from my birdhouse's roving room...

so you may ask what is so special and to look for in the two pictures?

ah....you see swiftlets will mark territory too...like how dogs piss by hydrants and street furnitures...

you can tell by the wall markings that the swiftlets are flying in to the birdhouse and the more dense the markings, the more swiftlets there are in your birdhouse...in theory...

the other picture below shows the floor just before the entrance to the nesting room...

i.e. still the roving room....

another good sign is that feathers are seen not only below the birds nest in the nesting room but also in the roving room...

this clearly indicates that females swiftlets are being chased by male swiftlets in to their nesting room...where love takes place...

of course if you have a multi-storey birdhouse and depending on the design of the entrance to roving room, you may notice different numbers/ types of patches of the above...

my tip, roving room design equally important to nesting room design...
