Andris landet on a branch in front of nest.

He brings in a prey. a fish the fish tail is striped like a pike
I've been watching LSE for a very long time. I never saw a fish brought. it shows that they are very adaptable


the fish tail is good visible

That was an awesome catch Andris! Great job

i don't think i've paid attention to the time line the last few years

Last year Anna laid her egg on 26th April (she came back on nest on 12th April, like this year ;) ) so it can be any day now

good Morning everyone

5:48 Andris is testing the nest


6:03 Anna is doing the same



6:54 she is waiting for Andris

[Liz01]

8:41 Anna came in for a short nest defending against the goshawk.


9:26 she is back in the nest


9:47 she is testing it

It's not the timeline that counts. The precondition for developing an egg is, sufficient food beforehand. So we can hope, there was enough till now.

I'm not sure Anna liked yesterday fish

[Liz01]

I'm not sure Anna liked yesterday fish

I can't imagine that Anna ate the fish. she is not a osprey or white tailed eagle

she eats frogs and other amphibians. but fish But basically one says that where the black stork has a good habitat, the lesser spotted eagle can also exist there. i.e. moor, streams, meadows

Diet of the Lesser Spotted Eagle (Clanga pomarina) in Amvrakikos Wetlands National Park, Greece
The diet of the lesser spotted eagle (Clanga pomarina) was studied in the area that is now the Amvrakikos Wetlands National Park during the Spring periods of 2000 and 2002 by analysis of pellets and prey remains found at two active nest sites, in two different territories. Among 155 prey items collected, in terms of biomass, the diet was 43% reptiles, 30% birds, 24% mammals, 3% amphibians and 1% arthropods. The most important prey taxa were brown rat (Rattus norvegicus) at 19%, water snakes (Natrix spp.) at 11% and moorhen (Gallinula chloropus) at 11% composition. Despite a wide availability of semi-natural and agricultural habitats around the immediate nesting areas, the species seems to have invested in foraging largely on water-dependent animals. The species maintained only one or a maximum of two pairs in the wider region during the study, this being at the southwestern margin of its global breeding range. Conservation insights and recommendations are presented.

I'm still searching for LSE & fish I hope to find fish on the menu

Diet composition and food supply of the Lesser Spotted Eagle Clanga pomarina in the core area of its breeding range
Uģis Bergmanis

Methods
Cameras were installed at five nests of three pairs of the Lesser Spotted Eagle in eastern Latvia, to collect data on food items brought to the nests.

Results
Of 3109 identified prey items, small rodents (43.36%) and amphibians (44.81%) were the most important prey groups. The proportion of common (small rodents and amphibians) and uncommon (moles, birds and others) food items differed between nests and years. Among the common food items, the deficiency of small rodents in some years was compensated for by an increase in frogs and vice versa. Male eagles brought 66% of all food items to the nest. Females brought more amphibians and fewer rodents than did males. After hatching, the mean number of food items delivered to the nest was 6.9 per day. The main activity period of food delivery was between the 3rd to 7th hour after sunrise.

Conclusion
The alternative prey hypothesis explains the diet of the Lesser Spotted Eagle in our study area. Rodents and amphibians are food items of equal importance that can replace each other, depending on their availability. The increasing share of amphibians towards the end of the breeding season was mainly a result of an increasing proportion of prey items brought into the nest by females.

Interesting, greater spotted eagles (clanga, clanga) have fish on menu

The Greater Spotted Eagle was formerly included in the genus Aquila, with the scientific name Aquila clanga. It is closely related to the Little Spotted Eagle (Clanga pomarina).
The scientific name “clanga” is from Ancient Greek, meaning “scream” and giving this elegant raptor its French name “Aigle criard”.

The Greater Spotted Eagle is found in Europe, Asia, Indian Subcontinent, Africa, the Middle East and southern Asia.
During the breeding season, it usually frequents forest and woodland with adjacent wetlands used as foraging and feeding areas. But during winter, it can be found in wetlands and farmland, and also in forested habitats.
It feeds on various vertebrates, from small mammals, birds, amphibians and reptiles to small fish, and also carrion.
This species nests in a large structure made with sticks, placed below the canopy in deciduous tree. The male provides the food while the female incubates and rears the chick.

The Greater Spotted Eagle is threatened by habitat destruction, forestry operations, shooting in some parts of the range, and hybridization with C. pomarina. The species is suspected to be declining and is currently listed as Vulnerable.

The eagles are closely related. so fish seems unusual, but not impossible

Great info thank you Linzm
