Sky’s The Limit For Spruce, Cypress, Willow & Sequoia!

All four falcon chicks have fledged!  Spruce, Cypress, Willow and Sequoia have taken their first flights without any reports of trouble.  Daniel is working hard to bring food to the juveniles wherever they are perched.  At this age they are not skilled hunters and still depend on their parents to provide meals and will vocalize loudly if they need food or assistance from their parents. Go this website to hear what the vocalizations of a peregrine falcon sounds like:

Within the next few weeks they will be able to capture food on their own.  The young peregrines are difficult to tell apart from their parents but can be seen perching on the Liberty Savings Tower or nearby buildings in downtown Dayton.  This is the first time Dayton and Daniel have raised four chicks.  At this time Spruce, Cypress, Willow and Sequoia have passed many hurdles and this nesting season can be considered a success.  With the state delisting of the peregrine as a threatened species in 2015 the young peregrines are now part of the success story of the recovery of the peregrine falcon population in Ohio.  The Dayton nest is part of a sample monitoring program in Ohio and data from the FalconCam will be submitted to the Ohio Department of Natural Resources – Division of Wildlife including the continued presence of the pair at the Dayton nest, the number of eggs laid, the number of eggs hatched, and the number of offspring that fledge.  As long as none of the young peregrines need human assistance they will stay in the area until the end of summer.  When the youngsters have enough skills they will leave Daniel and Dayton to find their own territories and hopefully one day raise young of their own.

The FalconCam stream will be turned off soon but if any significant events occur they will be posted.

A special “thank you” to our sponsor for their support with the 2016 Falcon Cam season.

Up Up and Away!

The juvenile falcons are starting to take their first flights!  The two older chicks were the first to take to the roof behind the nest box.  Last week they spent time on the roof behind the next box stretching their wings.  The two juveniles that hatched a few days later than their siblings left the nest box soon after and began practice hops and stretching their wings on the roof behind the next box.  Names were selected for the chicks through a contest on the Boonshoft Museum Facebook page and the winning names are Spruce, Cypress, Willow and Sequoia.  On Tuesday one of the juveniles made it to the ledge near the 17th floor of the Liberty Tower.

Dayton and Daniel still remain close by and provide food for the juvenile birds and protect them.  Once all the young falcons have taken their first flights they will be in flight training.  Dayton and Daniel will assist them as their flight instinct is developed.  Practice flights with parents nearby to keep the area clear of predators allow the youngsters to develop their skills.  The young birds will practice hunting with their parents passing pre-caught prey to them to help them to refine their skills.  Visits to the nest box will be infrequent and the birds will only rarely be seen in the nest box.  This is a good time to visit the nest site downtown as the birds can be seen in their practice flights over the Liberty Savings Tower in downtown Dayton.   The young peregrines are about six weeks old and are beginning to practice the skills they need to survive independently in the future.  They have passed their first hurdles but are still inexperienced.  The fledglings are as large as their parents and are hard to differentiate from Daniel and Dayton by their appearance while in flight downtown.  Dayton, Daniel and their four young falcons are all doing well and we continue to have no reports of any problems.  If the young falcons have gotten into any trouble they have been able to solve it themselves and are one step closer to being independent of their parents.

Falcon Chicks Update & Naming Contest!

The young peregrines have grown quickly and at almost six weeks old they are preparing to take their first flights.  Over the past few days the chicks have been stretching their wings often.  The white fluffy feathers of the chicks have been completely replaced by the darker adult feathers.  Juvenile  falcons have longer flight feathers than the adults to make it easier to learn the flying skills needed to become an excellent hunter in their first year.  The two older chicks are spending time on the roof behind the nest box and have no downy feathers remaining.   This large space is perfect for strengthening their wings with test hops and flapping.  Fledging is the name of the process of young birds learning to fly.  The chicks usually start fledging around six weeks old.  If you don’t see them on the camera image it is because they are practicing leaving the nest box by walking on the ledges and the roof.   After stretching and flapping their wings, their first flight will be from the 22nd floor where the nest box is located.  This is a view from the sidewalk in front of the Liberty Savings Tower.

The two chicks that hatched slightly later than their siblings still have some downy white feathers remaining and are a few days behind the other two.  Dayton and Daniel continue to keep a close eye on the chicks and are always nearby.

One More Chick Makes Four For Dayton’s Falcons!

The fourth egg that was thought to be infertile has hatched!  The third chick is almost the same size as it’s siblings now but the fourth chick is significantly smaller since it hatched almost a week after the first two.  All chicks are being fed by the parents and the smallest one stretches his neck up in the front to enable him to get food with the others.  In this image you can see one of the first meals for the new chick.  He is closest to the parent but has a hard time reaching as tall as his siblings.

On Monday both parents were seen working hard to care for the chicks.  Daniel and Dayton have never raised four chicks before so they will be busy keeping them fed!  Both parents have been observed feeding the chicks and keeping them warm in the mornings.  The chicks can be seen resting by laying down on their chests when they temperatures are warmer.  When it is cool one of the parents provides warmth by sitting on them.  In this image a freshly caught bird arrives for the family meal.

Falcon Chicks Are Here!

Dayton and Daniel’s eggs hatched!  On Sunday afternoon one chick was visible in the nest.  Later Sunday evening a second chick hatched.  If all progresses normally, the chicks will be the same size as their parents within six weeks.  At this link you can see images of how fast the chicks will grow:

http://www.peregrine-foundation.ca/info/ageguide.html

During the first 24 hours after hatching the chicks will use energy from the remaining yolk sac that they had while still in the egg.  Within a day the female will begin feeding the chick.  The baby chicks eat the same food as their parents, mostly birds brought to the nest by the male.  The female will tear tiny pieces using her beak and feed them to the chicks.

In this image you can see one of the parents eating a meal just outside the nest box to the right side of the image while the oldest chick sits in the nest box.  Within hours of this meal a second chick hatches.  The chicks are called eyases and, like most babies, they eat a lot.  They will double their weight in only six days!

In order to hatch from the eggs the chicks used a sharp tip on their beak called a beak tooth to pip out of the shell.  A special muscle also developed while in the egg along the back of the neck that assists the chicks in hatching called the hatching muscle. Some of the egg shells are still visible in the nest with a reddish brown outside and white on the inside of the cracked shell.  This year incubation went a little longer than estimated.  Even though the eggs are laid days apart they typically synchronize to hatch around the same date.  In this image from around 8 p.m. Sunday two chicks peak out from the adult peregrine.  The babies cannot thermoregulate well until about 10 days old so the parents continue to sit on them to keep them warm.

Update

Surprise! A new chick was born! There are now three Falcon chicks as of this morning.

Four Eggs For Dayton’s Falcons

Dayton and Daniel have four eggs in the nest!  Peregrine falcons lay an average of four eggs in a clutch with each egg laid a few days apart.   Dayton laid her first egg on March 10.  This is earlier than in previous years, possibly due to the unseasonably warm weather.  Last year she laid her first egg on March 18.  Incubation of the eggs starts toward the end of egg laying and the eggs will synchronize to hatch around the same time.  Incubation takes 29 to 32 days.  Dayton started closely sitting on the eggs by March 14 so hatching could take place as early April 11.  For now Dayton spends all of her time warming the eggs and turning them.  She is observant of any dangers outside the nest but Daniel is nearby protecting their territory.  Occasionally he will come to the nest to relieve Dayton of her incubation duties and provide her with food.

The falcons can be observed wiggling on the eggs to press the bare skin on the chest, called the brood patch, down on the eggs to keep them warm.  In species where only the female incubates the eggs the male doesn’t develop a brood patch.  Male and female peregrines both have brood patches because they share incubation of the eggs.  If you watch the Falcon Cam you’ll see the adult peregrines rock side-to-side as they settle on the nest.  This rocking opens the feathers that have curled over the brood patch and puts their skin in contact with the eggs.

Dayton turns the eggs every hour or so during the incubation process.  Both parents will work to maintain the ideal temperature of 99.5 F. Occasionally, the eggs may be left alone for short periods, but one of the birds will always be nearby keeping a close watch over them.

Dayton and Daniel are typically very successful raising their chicks but sometimes the young peregrines run into trouble later on.  Recently one of their chicks from last year, a male named Harrison, was injured and needed help.  Harrison was brought to the Glen Helen Raptor Center where he spent time recovering from wounds on one wing.  Harrison made a full recovery and was able to be released in Springfield in a territory not already held by other peregrines.  To learn more about Glen Helen Raptor Center go to this link:
