Barn owls Tommy and Tuppence nested in an owl box installed in a backyard in Rancho Bernardo, California. In December 2010, they were found in the box with Tuppence laying eggs starting in January. By late February, six eggs had hatched including chicks named Soren and Eglantine. While the chicks grew, their parents provided food. By early April, Soren and Eglantine were flying. A month later, they left the nest. Tommy and Tuppence may lay another clutch of eggs in late 2020 or early 2021.

Barn Owls of Rancho Bernardo, California
Over 200 owl species in the world Most belong to the Strigidae family Barn owls belong to the family Tytonidae Scientific name Tyto alba means white bird The other common owl in Southern California is the Great Horned Owl
They control rodents which carry diseases and destroy crops and gardens Nesting pair can eat 2000 rodents in a nesting season Encouraged to nest nearby Holes made in barns or other structures Owl boxes secured to trees or put on top of tall poles Attractive Large eyes / heart-shaped face Barn Owl Drawing - 1508
Wingspan of about 4 feet Cant move their eyes in their sockets, but can turn their heads 270 degrees Up and down / left and right Excellent night vision Best hearing of any animal on earth Offset ears in satellite dish face Completely silent flight Comb-like front edge on outer feathers
On our backyard hillside Fifteen feet high Next to pine and palm trees Allows a glide path to the entrance Two wireless network cameras Fledge Platform Safe and dry
Owl box installed 9/16/2010 Screeching heard and two owls circling at night Dec. 4, 5 and 6 Morning of 12/7 we find Tuppence In the box all day, gone all night The Dec. 13th Owl Tantrum Young female owls imprint a new home in their minds by cleaning it up screeching and scratching at the floor and the walls with their talons. Tom Stephan
Evening of Dec. 14th we found Tommy in the box with Tuppence They went off later to go hunting But after that, both stayed together in the box during the day Barn owls stay with the same mate for life And they are very affectionate towards one another
Rest of December Together in the box during the day Sleeping, standing on one leg Early evening, she would hen peck him out the door to go hunting The treats he brought back were quickly devoured Jan. 6th nesting activity begins with owl pellets
On Jan. 8th the camera showed the first egg Tommy seemed proud Tuppence seemed clueless Night picture shows nest of pellet material New eggs are laid every 2 days Barn owls can lay up to 16 eggs! Tommy often guarded the door between hunting trips to stock the pantry A total of six eggs were laid by Jan. 21st
Barn owls eggs take about 30 days to hatch Tuppences job is to keep the eggs warm and safe Tommys job is to bring her food Often, while on the nest, Tuppence will groom Barn owls must keep their feathers clean Tuppence must keep eating to stay healthy Adult barn owls often swallow rats and even rabbits whole!
On February 9th we welcomed the first barn owl chick into the world How Soren and his sister got their names How Mommy Tuppence feeds her new chicks The chicks hatch every two days At first they have no feathers and their eyes are closed When not feeding them Tuppence keeps them warm with her brood patch Look at all the food in the pantry!
Downy feathers begin to grow and so does the noise level in the box Owl chicks start out making faint snores That changes to hisses and scratching calls when food is delivered to the box The chicks also become more active They can lift their heads and move around Sometimes Mommy can keep them under her brood patch (especially that Soren) Mommy will leave the box to stretch her wings, but not for very long
Barn owl chicks double in size every couple of days As they grow, they get more demanding to be fed At first Mom feeds them Then they try to feed themselves (especially if Mom isnt in the box) And in not too long, they are swallowing rodents whole! [ Videos can be found on: www.OwlBeSeeingYou.com ]
It takes two months for an owl chicks feathers to grow out so that they can fly
Six eggs were laid, but only two chicks survived, Soren and Eglantine Two chicks died shortly after hatching One chick was just too small to get its share of food One chick looked healthy but died suddenly, probably of a virus In nature, very few barn owls live to be a year old Thats why they lay so many eggs Soren and Eglantine turned out to be fun loving siblings!
Right on schedule (about two months after hatching early April) the chicks were flying around the box and in the nearby trees Their parents would go off with them, teaching them to hunt One month later, they were both gone for good
Tuppence has been in the box on and off for the last few weeks Sometimes, like yesterday, both owls were in the box It appears likely there will be another clutch of eggs laid, probably in December or January
